Since Jira 8.4, when installing my plugin in Jira dev mode (atlassian-run/debug) a UI error shows up stating: An unexpected error occurred. refer to the logs for more information. This is now happening in Jira LTS 8.5.14 and 9.3.1.

This didn't happen before and no code changes were involved. There is nothing in the logs about this error. How can I try to resolve this?

Hi @roman.z,

Yes, I found this bug. I hope Atlassian fixes it soon.

Thank you @Melo . Yup, found that one as well, at least it's documented as it's a pretty serious issue atm.
