You opted for speed from this bot. Let's conjure up an answer right now!
The error message:
indicates that Prisma Migrate cannot connect to the database server at the specified address for the shadow database, even though other tools (Studio, db pull, psql) can connect.
Based on the knowledge sources, here are some possible causes and troubleshooting steps:
1. Port or Connection Mismatch: Double-check that your
DATABASE_URL in .env is set to use localhost:5433 and that the database is actually listening on that port. Sometimes, other tools might connect via a different port or socket.
2. Shadow Database URL: Prisma creates a shadow database during migrate dev. If your database user does not have permission to create new databases, or if the server is configured to block new connections or database creation, this can cause P1001. You can explicitly set a shadowDatabaseUrl in your schema.prisma to control where the shadow DB is created and ensure it points to a reachable server and port.
3. Resource Constraints: If your database server is under heavy load or has limited resources, the shadow database creation might fail intermittently, especially with many migrations or on small machines. Upgrading your database instance or squashing migrations can help in such cases Migration failed to apply cleanly to shadow database.
4. Misleading Error Message: Sometimes, the P1001 error is a red herring and the real issue is elsewhere (e.g., permissions, resource exhaustion, or a SQL error in a migration). Enabling query logging on your database can help identify the real cause Migration failed to apply cleanly to shadow database.
5. Docker/Networking Issues: If running in Docker, ensure that the network configuration allows connections to localhost:54
33 from the Prisma process Unstable connection on Docker for M1 Macs.
If none of these resolve the issue, please provide more details about your environment and configuration.

Hey guys, going to have to leave Prisma @ this rate, have been left in the dark unable to update our DB with Prisma.
We'd appriciate some supprt and a fix to this.
Hey @πΏπΆπΈπ½πΎπ!
I assume you are trying to run
npx prisma migrate dev command?
Have you specified a shadowDatabaseUrl ?
If you are prototyping and don't need migration history then you can use npx prisma db push to push the changes.Yes & yes, we do want the migration history
What is your shadowDatabaseUrl, can you share it after removing username/password?
Is it running on port 5433?
This error would mean that prisma is not able to connect to the database.
Did you try connecting to the shadow database via a Database IDE like pgAdmin, Tableplus etc?
Are you able to connect?
