Have you tried removing the client output and let the generator find it itself?

[nade]

I had this error before adding clientOutput and adding it didn't do anything.

[Arthur Fiorette]

Very weid, where are the relative locations to your prisma client output?

[nade]

They’re all in node_modules, just like the default location.

[Arthur Fiorette]

Can you provide a reproducible example so that I can test out?

You can also try to change this piece of code in your node modules (same path, but in the dist folder, not src)

prisma-json-types-generator/src/file/reader.ts

Lines 25 to 33 in 5cff770

 declaration.sourcePath = overrideTarget 
   ? overrideTarget.startsWith('./') 
     ? path.resolve(schemaTarget!, overrideTarget) 
     : require.resolve(overrideTarget) 
   : path.resolve( 
       // prisma client directory 
       path.dirname(require.resolve('.prisma/client')), 
       'index.d.ts' 
     );

@arthurfiorette
It also does not work for me.

Here is the reproducible example:

1. pnpm create t3-app@latest prisma-json --noGit --CI --prisma
2. cd prisma-json
3. pnpm install prisma-json-types-generator
4. add the "prisma-json-types-generator" generator copied from the readme of the github repo under the prisma client generator

schema.prisma

// This is your Prisma schema file,
// learn more about it in the docs: https://pris.ly/d/prisma-schema

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

generator test {
    provider     = "prisma-json-types-generator"
    namespace    = "PrismaJson"
    clientOutput = "./custom.d.ts"
}

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

model Example {
    id        String   @id @default(cuid())
    createdAt DateTime @default(now())
    updatedAt DateTime @updatedAt
}

5. npx prisma generate

Environment variables loaded from .env
Prisma schema loaded from prisma/schema.prisma
Error:

ENOTDIR: not a directory, open '{path-to-project-folder}/prisma-json/prisma/schema.prisma/custom.d.ts'

6. Remove clientOutput from schema.prisma

schema.prisma

// This is your Prisma schema file,
// learn more about it in the docs: https://pris.ly/d/prisma-schema

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

generator test {
    provider     = "prisma-json-types-generator"
    namespace    = "PrismaJson"
}

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

model Example {
    id        String   @id @default(cuid())
    createdAt DateTime @default(now())
    updatedAt DateTime @updatedAt
}

7. npx prisma generate

[Arthur Fiorette]

Finally I could reproduce it myself. Pnpm stores its dependencies under .pnpm folder and creates symbolic links from node_modules/NAME to node_modules/.pnpm/NAME@version, that's why we couldn't find .prisma folder.

The generated output should be node_modules/.pnpm/@prisma+client@4.9.0_prisma@4.9.0/node_modules/.prisma/client.

Hey @NADESHIKON & @itsyoboieltr, just released 2.0.0 with this fix.

Also, there's a new syntax for types.

model Test {
  /// [NormalType]
  field Json

  /// [OptionalType]
  field2 Json

  /// [ArrayType]
  field3 Json
}
