prisma generate is unable to generate typegraphql

Bug description

I am running a docker container with node:14-alpine on my Mac. The npx prisma generate command used to work fine before.

After I witched from 2.25.0 to 3.2.1 the generate command stopped working, although this may not be the issue. I get this now :

Environment variables loaded from .env Prisma schema loaded from prisma/schema.prisma Error: ✔ Generated Prisma Client (3.2.1) to ./node_modules/@prisma/client in 718ms

Error: EIO: i/o error, open '/app/node_modules/@generated/type-graphql/resolvers/crud/model/FindFirstModelResolver.js

During this time, I added more models to the schema and my schema is around 700 lines.

The error changes each time I run the generate command. I suspect the large number of files created during the generation to be the issue. I can see the files in the @generated folder, but most of those are blank.

When I run the same container on an ubuntu machine, I get the too many files error.

How to reproduce

1. run npx prisma generate
2. the typegraphql generation gives an error

Expected behavior

No response

Prisma information

schema is around 700 lines.

Thanks @janpio, I think the issue is with typegraphql-prisma. But I will try and find out if this works with the older prisma.

I use typegraphql-prisma as well, although my Prisma schema is smaller than yours (~250 lines, 22 models). This sounds like some problem in your environment/OS/filesystem. I don’t have a mac, I am running it on 1 year old version of WSL2… Note, that typegraphql-prisma generates lot of stuff and the library from version 0.16.2 can limit the amount of generated (potentially never used) stuff. Try to consider if you can limit the generated files.
