@NicolaGenesinJetty is attempting to deploy a commit to the Prisma Team on Vercel.

A member of the Team first needs to authorize it.

Did you open a bug report in prisma/prisma about this? That should probably not be happening - so a description of what you are seeing would be interesting.

@NicolaGenesinJetty Could you check your schema? It should look like this:

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["referentialIntegrity"]
}

datasource db {
  provider     = "mysql"
  url          = env("DATABASE_URL")
  relationMode = "prisma" // <--- Make sure that this line is present
}

This is mentioned in the first step here https://www.prisma.io/docs/getting-started/setup-prisma/add-to-existing-project/relational-databases/connect-your-database-typescript-planetscale

Maybe it could use a reminder on https://www.prisma.io/docs/getting-started/setup-prisma/add-to-existing-project/relational-databases/introspection-node-planetscale

@Jolg42 I was missing that relationMode line. I've added it but npx prisma db pull removes virtual relations anyway.

[Jolg42]

@NicolaGenesinJetty Could you give us info we can use to get to a reproduction? We are very interested into checking this.

The best would be to open a bug report here

whoops I just checked the "Describe this PR" and it's empty. Weird, sorry about this.

Submitted bug report with more infos here prisma/prisma#16100
