Can't use a locally hosted postgresql database on Prisma.

It keeps throwing the error 'Error validating datasource

db

db

: the URL must start with the protocol

prisma://

prisma://

', though I see many people using it all the time.

My schema is

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

, and then normal models. I genuinely cannot figure out for the life of me on why I can't do this.
