When running npx prisma migrate dev for the 2nd time I get this error

Environment variables loaded from ../.env
Prisma schema loaded from schema.prisma
Datasource "db": PostgreSQL database "test-dev", schema "public" at "test-dev.postgres.database.azure.com:5432"

How to reproduce

• create a schema file with shadowDatabaseUrl
• run npx prisma migrate dev, tables gets created, migration gets created
• run npx prisma migrate dev again. you encounter the error above

Expected behavior

• it should either create a new migration file if there are changes or return with no errors

At least for me the issue seems to be with postgresql hosted on azure, running the action against the database on azure resulted on the same error:

For anyone having the same issue I found this stackoverflow thread that solved it for me: https://stackoverflow.com/questions/41207259/no-schema-has-been-selected-to-create-in-error#:~:text=You get this error when,users ).

As in that thread granting create and usage permissions on the public schema had the migrations working for me again:

grant usage on schema public to public; grant create on schema public to public;
