In a fresh repository with discussions enabled it is currently not possible the remove any of the default discussion categories. Every attempt results in HTTP 502.
Thanks for letting us know - it’s doing the same for me. I’ve opened an issue for the team.
Can you post a link to the issue or how would I know that the issue has been resolved?
I’m afraid the issue isn’t in a public repository but I’ll do my best to follow up!
@camueller - I can see that a fix has been merged for this issue. Please let me know if you’re still having trouble with it!
Removing one default category worked.
Trying to remove the second one (“Ideas …”) produced HTTP 502 initially but succeeded on second try.
