"Update Issue Custom Field" Post Function Stopped Working

[Juan Raven]

Hello!

I have a post function set up to set a custom field to the current user upon transition. The post function has been working fine for months until a day ago I can't think of what I did to cause the issue.

The last change I did to the workflow was add a "Field Required Validator" on a Friday. That Friday, Saturday, Sunday, and Monday, everything seemed to work fine. I didn't touch the workflow. Then on Tuesday, the post function seemed to not be working anymore.

By the way, the post function does seem to be working for one user, but not any others. We're using Jira Cloud with about 10 users.

Can someone please help me troubleshoot? I'm fairly new to administering Jira, so please bare with me.

Thanks!
