According to Nikolas Burk, you can also run

    npx prisma db push

instead of the npx prisma migrate dev command.

Alternatively, according to Paul Liu:

1. Set up a local DB. I am using PostgreSQL
2. Change your prisma .env file to local DB
3. Delete prisma/migrations folder
4. Run npx prisma migrate dev --name my_deploy to start a new migration
5. Change your prisma .env file back to the development DB
6. Apply the migration by passing the migration folder name generated in step 4 by running npx prisma migrate resolve --applied my_deploy --preview-feature
