To upvote this and add another use case: Prevent duplicate job.
Or at least, to simplify such processes for users that are not that familiar with the code node and maybe reduce amount of listings I have to check whether there’s something running shown in between the last X results ;-).
I guess that shouldn’t be too complex as it is just a filter checking for stoppedAt === null to integrate?
At least that’s the workaround I am using currently in a code node (with some other additional search/filter parameters as the workflow is dynamized through parameters for multiple cases) .
