Attempt to recreate deleted chat channel with the same name (still) fails

When I try to create a new channel (named “general”, same for the slug) the following error shows up in the logs (nothing is happening on frontend).

No “Closed” channels are shown.

I might have had a general channel in the past - and probably deleted it (is it default?)

Can not repro with another random slug (create > delete > create works just fine).

Failed to handle exception in exception app middleware : ActiveRecord::RecordNotUnique : PG::UniqueViolation: ERROR:  duplicate key value violates unique constraint "index_chat_channels_on_slug"
DETAIL:  Key (slug)=(general) already exists.
