Workflow statuses are often broken. I did not figured out why yet. But I
see two causes that can be fixed:
- statuses calculation are really complicated today, just to spare a
call to the database
- job is not indempotent, it is using the combination of the previous
statuses + the update to calculate the new statuses. Which means that
once broken, next updates will be broken as well
Instead, we now:
- fetch workflow versions
- get the statuses from these.
It simplifies the code and make the job indempotent.
