There was a problem hiding this comment.
I was reading the text multiple times and still have trouble understanding the query logic... but I can confirm it fixes the problem.

closes: #44245
Cause
The query for fetching the stats of task instances groups them by
task_id,run_id,state, andtry_number. However, usingtry_numberfor dynamic mapped tasks leads to incorrect results as individual tasks within the mapping might have differenttry_numbervalues.Example
Let's say that within a dynamic mapped task there were 10 expansions - 4 of them failed in the first time and reran (i.e.,
try_number = 2).In this case, the API response will eventually show only statistics regarding the most recent
try_number.Note
Intermediate results might not exactly follow the latter pattern, as they also depend on the
TaskInstance.stateparameter of thegroup_by.Solution
In the query, avoid grouping by
try_numberonly for dynamic mapped tasks (map_index != -1).^ Add meaningful description above
