Prisma 1.34 fails to run a migration. I tried all I can and still same issue. I don’t want to drop tables & re-build from scratch again

Hey @Jaafari El Housseine 👋 As the migration didn’t go through, could you check by dropping the last entry in the migration table and re-migrate?

I did, still same issue

Then unfortunately setting up from scratch would be the way to go You would need to manually bring the current schema and database in sync. Dump the SQL, do an initial migration, load the data.

😕 I did it multiple times now. Not working, the issue happens to only one Table. I tried other tables & Prisma executed correctly
