i only had one project with one chat. i integrated it with supabase. after some coding, i linked it to a new github repo. after this, i found the project to be duplicated and the original one to not work anymore (could not find the supabase keys in the env). did not manage to fix it even after a refresh of the supabase integration.
so i started a third new clean project with a new chat. started from scratch. after adding supabase again, from scratch to vercel, the current chat moved to one of the older projects (!)
and one of the old chats moved to the new project!
this is a pretty wild bug.
i’m just using the platform and unexpected things happen
