feat(shared,trpc): save triggers as a set with the automation - #6534
Conversation
Triggers are edited as part of the automation, not one row at a time, so the surface is a replace-the-set on automation.create/update rather than per-trigger CRUD. Validation lives in @superset/shared so the editor runs exactly the checks the API enforces, and it distinguishes two levels: a draft may be half-configured, so the form can hold "Draft opened in [Select Repos]" with nothing chosen, while describeTriggerProblems reports what blocks Save, per trigger and per field. The set is matched by id rather than cleared and reinserted: a trigger row carries a webhook's signing key and a schedule's next run, neither of which the editor sees, and recreating would roll the key and reschedule an automation that was only renamed. GitHub configs are a union on the event, since the filters differ — a comment has both a comment author and a PR author, a push has neither. Top-level rrule still works and folds into a single schedule trigger, so the CLI, SDK, MCP and desktop keep working until they move over.
📝 WalkthroughWalkthroughThe change adds shared automation-trigger schemas and validation, accepts trigger sets in automation create and update inputs, persists trigger rows, supports event-only automations, and preserves legacy RRule synchronization when trigger sets are not provided. ChangesAutomation trigger sets
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to Automation updates can create invalid schedule state, leave trigger routing and scheduling inconsistent after type changes, and report a next run that differs from what is stored. These correctness issues can affect saved automations and runtime dispatch, so the PR is not merge-ready until they are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

The header documents a triggerSchema that this file does not export.
Lines 9-12 describe two levels: draftTriggerSchema and triggerSchema. Only draftTriggerSchema exists. Saveability is enforced by describeTriggerProblems, not by a second schema. A reader of this shared module will look for an export that is not there. Update the header to describe the actual pair, or add the missing schema.
Separately, Zod 4 exposes z.uuid() as the standalone UUID format. z.string().uuid() on Line 160 is the legacy form.

Validate schedule recurrence fields before entering the write transaction.
rrule and timezone currently accept arbitrary non-empty strings, so invalid recurrence or timezone values reach runtime calculation and can surface as a 500 instead of a field-level validation error. Add recurrence parsing checks to describeTriggerProblems, validate timezone as an IANA zone, and use the current ISO datetime validator for dtstart.

The update path never writes kind, so a trigger that changes type leaves kind and config inconsistent.
The insert at Line 118 sets kind: config.kind. The update at Lines 104-108 sets only config, enabled, and nextRunAt. A caller can send an existing trigger id with a config of a different kind. draftTriggerSchema accepts that, and existingById matches by id alone. The row then keeps its old kind while storing the new config.
Two consequences follow:
kindis the routing column.syncScheduleTriggerinpackages/trpc/src/router/automation/helpers.tstargets the partial unique index withsql\kind = 'schedule'`, and thelist/getqueries inautomation.tsjoin on the schedule trigger. A row withkind = 'schedule'` and a GitHub config would be joined and read as a schedule.recurrenceChangedreturnsfalsewhennext.kind !== "schedule". A schedule row converted to a GitHub trigger therefore keepsprevious.nextRunAt. The dispatcher indexesnextRunAt, so that row can fire on a stale timestamp.
Write kind on update, and clear nextRunAt when the kind is no longer schedule.
🐛 Proposed fix
function recurrenceChanged(
next: DraftTrigger["config"],
previous: TriggerConfig | null,
): boolean {
- if (next.kind !== "schedule") return false;
+ // A kind change always invalidates the stored next run.

previous.rrule !== next.rrule ||
previous.dtstart !== next.dtstart ||

);
} const [row] = await tx
.update(automationTriggers)
- .set({ config, enabled: trigger.enabled, nextRunAt })
+ .set({ kind: config.kind, config, enabled: trigger.enabled, nextRunAt })
.where(eq(automationTriggers.id, previous.id))
.returning({ id: automationTriggers.id });With recurrenceChanged returning true on a kind change, nextRunAtFor returns null for the non-schedule config, so the stale timestamp is cleared.

Reverse-engineered by driving the live automations UI rather than inferring from screenshots. Corrections: - actor is anyone | me | specific people, not org_members - GitHub events are a real 21-value list, including the nested variants: pr_review_submitted (approved/changes_requested/commented/any), review_thread (resolved/unresolved/any), workflow_run (success/failure/cancelled/any) - comment events carry a free-text body filter with a regex toggle, which no version of this schema had - Slack, Linear and Sentry take one event each, not an array, and their event lists are now the real ones - Slack reactions require an emoji, which is now checked
A trigger set may contain no schedule — an event-driven automation is the normal case for GitHub or Slack — and three things assumed otherwise: - list, get and getAutomationForUser inner-joined the schedule trigger, so an automation without one vanished from every listing. It did not look broken, it looked deleted. - rrule was still required on create, so an event-only automation could not be expressed at all. - create and update reported the schedule from their input, describing one that may never have been written or was just removed. Schedule fields are now nullable throughout and responses are built from what was saved. The inner join was correct when written: every automation had exactly one schedule, so inner and left were equivalent. The trigger set broke that assumption and the join was not revisited.

Fixed in bb28434. The Critical finding was correct and is the most important thing in this PR. An event-only automation was invisible. That join was correct when written: at the time every automation had exactly one schedule trigger, so inner and left were equivalent. The trigger set broke that invariant and I didn't revisit the join. Worse, I'd written the hazard down myself in #6531 as the reason to block deleting a schedule trigger — then built a set-save that deletes any trigger not in the set. Demonstrated against Postgres 16, with one scheduled and one event-only automation:
That third row matters: making automations visible must not make event-only ones start firing on a schedule they don't have. Also fixed from the same review:

The reported nextRunAt can differ from the value that was persisted.
withSchedule receives the draft input.triggers, not the rows that saveTriggerSet returns. It then recomputes nextRunAt from new Date().
saveTriggerSet does not always write that value. For an existing trigger whose recurrence did not change, it keeps previous.nextRunAt (see packages/trpc/src/router/automation/triggerSet.ts lines 100-104). A retained past-due nextRunAt is therefore reported as the next future occurrence, so the response contradicts the row the dispatcher reads.
saveTriggerSet already returns the saved rows. Pass those rows to withSchedule and read nextRunAt from the row instead of recomputing.

The left join makes row.rrule nullable, but safeDescribeRrule only guards against a null row.
safeDescribeRrule (Lines 798-805) checks if (!row) return "". After this join change, row is always present while row.rrule can be null for an event-only automation. describeSchedule(row.rrule) then runs with null. If it throws, the catch returns row.rrule, so scheduleText becomes null at runtime although the declared return type is string.
The same path applies to get at Line 230 and Line 248.
Guard the field, not the row.

Drizzle ORM 0.45.2 leftJoin select object spread nullable inferred type SQL aliased expression source
💡 Result:
In Drizzle ORM, particularly around version 0.45.2, type inference for fields selected from a LEFT JOIN is governed by the join's nullability rules [1][2]. Because a left join can result in no matching rows, Drizzle automatically marks fields from the joined table as nullable [1]. Regarding the specific behaviors you encountered: 1. SQL Aliased Expressions: Drizzle often cannot automatically infer that an sql aliased expression should become nullable after a left join [3]. If you have an expression like sql<string> in a subquery or select, it will remain string even if the table is left-joined [3]. You must explicitly cast it to include null in your type definition, for example: sql<string | null>... [1][3]. 2. Object Spread and Partial Selects: Using the object spread operator (...) with getTableColumns() is a common way to select multiple fields, but it bypasses Drizzle's sophisticated internal logic that manages nullability for nested selects [1][4]. Drizzle's official recommendation for handling many columns without getting a "plethora of nullable fields" is to use the nested select object syntax [1]: await db.select({ mainField: table.field, joinedTable: { field1: joinedTable.field1, field2: joinedTable.field2, } }).from(table).leftJoin(joinedTable,...) When using this nested syntax, Drizzle's type inference automatically makes the entire joined object (joinedTable) nullable ({...} | null) rather than making every individual column within it nullable [1]. 3. Version 0.45.2: This version was primarily a security release addressing potential SQL injection vulnerabilities related to sql.identifier() and sql.as() [5][6]. It did not introduce major breaking changes to the type inference engine for joins [7][6]. If you find that your types are incorrectly inferred as non-nullable, it is often due to using getTableColumns or spread operators instead of explicit nested objects, or relying on sql templates without manual nullability typing [1][3].

Preserve LEFT JOIN nullability for computed schedule fields
Drizzle widens joined Column selections but leaves SQL.Aliased selections unchanged. Therefore, rrule, dtstart, and timezone remain non-nullable, while only nextRunAt becomes nullable. Type the computed aliases as nullable, and use a mapWith decoder that returns Date | null for dtstart.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Both rrule and triggers can be supplied, and the top-level rrule is then discarded silently.
The first refinement accepts a request that carries both shapes. In automation.ts create, the input.triggers branch runs and legacySchedule is never persisted. The caller receives no error and no signal that its rrule was ignored.
If both shapes must not coexist, reject the combination here.
♻️ Proposed refinement

})If a client is expected to send both during migration, document the precedence in the schema comment instead.

Replaces the per-trigger CRUD approach in #6531 (now draft). Triggers are edited as part of the automation, so the surface is a replace-the-set on
automation.create/update.No migration.
Shared validation
Lives in
@superset/shared/automation-triggers, imported by both the editor and the API, so the form blocks Save on exactly what the server would reject rather than reimplementing the rules.It deliberately has two levels:
draftTriggerSchemaaccepts a half-configured trigger. The editor has to be able to hold "Draft opened in [Select Repos]" with nothing chosen yet — if the schema refused to represent that, the form couldn't hold its own in-progress state.describeTriggerProblemsreports what blocks Save, per trigger and per field, so a message can sit next to the control it belongs to.summarizeTriggerProblemsproduces the banner.The messages match the mockups: "Some triggers need additional configuration" and "Specify at least one repository."
It also catches more than one schedule per automation, which the partial unique index enforces in the database — better as a message next to the row than a constraint violation at save time.
Matched by id, not cleared and reinserted
A trigger row carries state the editor never sees: a webhook's signing key, and a schedule's next run. Clearing and reinserting would silently roll a key someone had already configured upstream, and reschedule an automation that was only renamed.
So rows present in the set are updated in place, rows absent are deleted, and the next run is only recomputed when the recurrence actually changed.
GitHub configs are a union on the event
The filters differ per event — "Any Comment by [Anyone] on a PR by [Anyone] in [Repos]" carries two independent actor scopes where "Draft opened" carries one. A single flat config with one
actorcan't express that, so the config discriminates onevent.includeForksstays the literalfalse: fork payloads carry attacker-controlled content into a checkout the agent runs in, so enabling it should be a schema change with a threat model attached.Verified against a real database
The actual
saveTriggerSetexecuted against Postgres 16, not reasoned about:Plus the shared validation itself: a half-configured trigger parses but reports a problem; a comment event requires both actors;
includeForks: true, unknown events, and an unknown kind are all rejected.Compatibility
Top-level
rrulestill works and folds into a single schedule trigger, so the CLI, SDK, MCP and desktop keep working until they move to sending a set. Same expand-contract shape as the column migration.Typecheck, lint and the full suite pass.

The editor UI, then webhook ingestion so event triggers actually fire.
