Seems to be fixed with this patch: FIX: Multiple topics may have the same post as its solution (#348) committed 02:21PM - 26 Mar 25 UTC (UTC) [imagen] nattsw …

Delete one of the SolvedTopic records via rails console: DiscourseSolved::SolvedTopic.where(answer_post_id:201795).last.destroy

Thank you. I’ve tried to access those, but I’m getting NameError: uninitialized constant SolvedTopic Any other ideas?

I’ve now connected to the database directly and deleted the record with the duplicate answer_post_id from discourse_solved_solved_topics. All good now. Thanks again for your quick reply!

Hm. discourse-solved was updated recently . There is a chance, that this error was thrown during database migration.

Yes, this happened during database migration.

Excellent! Thanks for the heads up — I’ve marked your post as solution.
