PANIC: column on null constraint violation error

[janpio]

When using prisma-test-utils via prisma-test-utils-automation, some databases (schemas from: https://github.com/prisma/database-schema-examples) fail with this error message:

Error in: chinook (postgres)
PrismaClientUnknownRequestError:

   970 /**

→  973 const seed = await client[methodName].create(

I don't know how you ran into this with Chinook. I could only observe this for the database mentioned below.

I am not fully sure what this is about yet, maybe inserting a record with the respective foreign key record not inserted yet.

The SQL shows that the table providers_individuals has a PK that is also a FK to the table providers. That is currently not supported in Prisma, so test-utils does not have any way to find out about that it should insert an existing providers.id here.
