The `_prisma_migrations` table still records migrations from the newer version as "applied," but the underlying database tables were modified, dropped, or never fully created. + +**How to fix:** + +#### Step 1 — Delete the failed migration entry and restart + +Remove the problematic migration from the history so it can be re-applied: + +```sql +-- View recent migrations +SELECT migration_name, finished_at, rolled_back_at, logs +FROM "_prisma_migrations" +ORDER BY started_at DESC +LIMIT 10; + +-- Delete the failed migration entry +DELETE FROM "_prisma_migrations" +WHERE migration_name = ''; +``` + +After deleting the entry, restart LiteLLM — it will re-apply the migration on startup. + +#### Step 2 — If that doesn't work, use `prisma db push` + +If deleting the migration entry and restarting doesn't resolve the issue, sync the schema directly: + +```bash +DATABASE_URL="" prisma db push +``` + +This bypasses migration history and forces the database schema to match the Prisma schema. + +--- + +### 2. `New migrations cannot be applied before the error is recovered from` + +**Cause:** A previous migration failed (recorded with an error in `_prisma_migrations`), and Prisma refuses to apply any new migrations until the failure is resolved. + +**How to fix:** + +1.

The `_prisma_migrations` table has stale entries for migrations that were partially applied or correspond to a schema state that no longer exists. + +**Fix:** + +1. Inspect the migration table for problematic entries: + +```sql +SELECT migration_name, started_at, finished_at, rolled_back_at, logs +FROM "_prisma_migrations" +ORDER BY started_at DESC +LIMIT 20; +``` + +2. For each migration that shouldn't be there (i.e., from the version you rolled back from), delete the entry: + ```sql + DELETE FROM "_prisma_migrations" WHERE migration_name = ''; + ``` + +3.
