Generating the js client with the Go client doesn't work

[matthewmueller]

Right now you get a rather unusual error if you have provider = "prisma-client-js". Tried generating a new Go client:

$ go run github.com/prisma/prisma-client-go generate
info: 2021/04/07 15:25:31 prisma cli doesn't exist, fetching... (this might take a few minutes)
info: 2021/04/07 15:26:07 prisma cli fetched successfully.

My schema looks like this:

// This is your Prisma schema file. Learn more in the
// documentation: https://pris.ly/d/prisma-schema

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

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["createMany", "groupBy", "orderByRelation"]
}

model User {
  id        Int      @id @default(autoincrement())
}

Figured it out,

generator client {
-  provider = "prisma-client-js"
+  provider = "go run github.com/prisma/prisma-client-go" 
  previewFeatures = ["createMany", "groupBy", "orderByRelation"]
}

Maybe we can improve the error message?

[garrensmith]

The go client is no longer supported.

[janpio]

That unfortunately doesn't change anything about the weirdness about the error message from the generator.

@matthewmueller Do I understand correctly that basically trying to generate a normal JS Client via the Go CLI leads to this unhelpful error message?

Correct

Needs to be fixed by Prisma core via https://github.com/prisma/prisma/issues/10564
