Null constraint violation on the fields: (`ownerId`)

With the following schema when I try and create a new Project I get then Null constraint violation for field ownerId which doesn't exist anymore

model Project {

  stitches  Stitch[]
  project   Project  @relation(fields: [projectId], references: [id])
}

  completed Boolean    @default(false)
  row       Row        @relation(fields: [rowId], references: [rowId])

}

  Single
  Increase
}

You've gone full bot mode! Let me fetch that AI answer for you ASAP. Based on the information in your schema and the error you're experiencing, it appears you're facing a null constraint violation for a field called ownerId that no longer exists in your schema. This issue is similar to the one described in Github Issue #26284, where removing a field from a schema can sometimes lead to constraint violations during migrations or operations. The error suggests that your database still has a constraint or column related to ownerId even though it's been removed from your Prisma schema. This commonly happens when: 1. You previously had a relation between Project and User (likely through an ownerId field) 2. You removed this relation from your schema (as evidenced by the commented out // projects Project[] in your User model) 3. But the database still has the column and/or constraint There are a few approaches to resolve this: 1. Check if there's a mismatch between your Prisma schema and the actual database schema. You might need to run a migration to properly remove the ownerId column. 2. If you're using migrations, you might need to create a new migration that explicitly drops the column or constraint. 3. In some cases, you might need to reset your database schema completely as described in this Prisma discussion: - Delete all migration files (rm -rf prisma/migrations) - Delete migration records from the database (DELETE FROM "_prisma_migrations";) - Create a new baseline migration - Apply the cleaned-up SQL script to the database If you're using prisma db push instead of migrations, try running it with the --force-reset flag to force a reset of the database schema to match your Prisma schema. Remember that these operations might result in data loss, so make sure to back up any important data before proceeding. 🤔 Alright, thanks for letting us know that there's still some help needed. A team member will reply to you shortly. In the meantime, please let us know any additional info, questions, or which parts of the answer may need clarification.

I completely deleted my database am still getting this error

That's strange. When exactly do you get this error? I assume while you are doing a query? To confirm, you PrismaClient is in sync with the schema.prisma file, correct?
