Hide the toast details panel when the payload is empty - #51338
Conversation
Error toasts render an expandable "Raw response" panel whenever a detail
payload is present. Callers pass caught errors straight through as
`response`, and an Error's own properties are non-enumerable, so
JSON.stringify returns "{}" without throwing. The panel opened on an
empty object, offering nothing the message didn't already say.
Derive hasDetail from the serialized payload instead of from the raw
value, and treat payloads that carry nothing ("{}", "[]", "null", "" and
the empty string) as no payload. The chevron is then hidden entirely
rather than revealing an empty block.
Fixed in ToastCard rather than at the call site: around 177 call sites
pass a caught error as `response`, so any of them can hit this.

- Around line 93-99: Update syntaxHighlight and the other detail-serialization
path to explicitly handle JSON.stringify returning undefined for top-level
functions or Symbols, treating the result as unavailable rather than allowing
fallback String(detail) text to keep the panel visible. Preserve existing
handling for serializable values and thrown serialization errors, and add
regression cases covering both non-serializable top-level types in each path.

JSON.stringify returns undefined, rather than throwing, for values with no JSON representation such as functions and symbols. detailText became undefined, the highlighter then threw on it, and the catch fell back to String(detail) — so the panel opened on a function body or Symbol(...) instead of staying hidden. Coalesce the missing result to an empty string and skip the highlighter when there's nothing to format.

Related issue: Resolves #50846
Uploading a custom package with an unsupported extension shows an error toast whose expandable "Raw response" panel contains nothing but
{}.Root cause
ToastCarddecides whether to render the panel from the raw prop:Callers pass a caught error straight through as
response—notify.error(${e}, { response: e }). AnError's own properties (message,stack) are non-enumerable, soJSON.stringifyreturns"{}"without throwing, which means the existingcatchfallback never runs. The panel then opens on an empty object.The issue points at
PackageForm.tsx, but that's one instance of a general problem: roughly 177 call sites across the frontend pass a caught error asresponse, so any of them can produce this. Fixing it at the single reported call site would leave the rest.Changes
In
frontend/components/ToastNotification/ToastCard.tsx, derivehasDetailfrom the serialized payload rather than the raw value, and treat payloads that carry nothing as no payload:hasDetailalready gates the chevron, the panel, and the card's--openclass, so the toggle disappears entirely instead of revealing an empty block. This matches the first option in the issue: the message text already carries the error, so there's nothing to disclose.Payloads with real content are untouched. Verified against the actual serializer:
JSON.stringify(x, null, 2)new Error("unsupported file extension: dmg")"{}"{}/[]/null/"""{}"/"[]"/"null"/'""'{ status: 422 }"{\n \"status\": 422\n}"{ message: "internal" }"{\n \"message\": \"internal\"\n}"Checklist for submitter

Testing
Added
ToastCard.tests.tsxcovering both directions:Error,{},[],null,"", and for no payload at all.All five suppression cases were confirmed to fail against the unfixed component, and the three "still shows" cases pass either way — they exist to catch the fix over-suppressing real API responses. The existing
ToastNotification.tests.tsxsuite passes unchanged, so thenotifyAPI's response resolution is unaffected.eslint,prettier, andtsc --noEmitare clean.Not done. Verified through the tests above and by checking the serializer's real output for each payload shape rather than assuming it.
