Hey there I am receiving this error in my schema

Error validating: A self-relation must have `onDelete` and `onUpdate` referential actions set to `NoAction` in one of the @relation attributes. (Implicit default `onDelete`: `SetNull`, and `onUpdate`: `Cascade`) Read more at <https://pris.ly/d/cyclic-referential-actions>

I am using mysql with planetscale

datasource db {
  provider             = "mysql"
  url                  = env("DATABASE_URL")
  referentialIntegrity = "prisma"
}

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

I am receiving the error on all relations (not only self-relations) which is weird. Also, the link given doesn't mention mysql (only mongodb and sql server) The error was not there before, It showed up out of nowhere.

Are you using 3.7.0? If yes it could be related to this https://github.com/prisma/prisma/issues/9931 Maybe open an issue and try downgrading to 3.6.0?
