"Dynamic require of "node:fs" is not supported" but only when using js processor with custom path

[AlvesJorge]

Question

Hey all, hope you are doing well.

I am planning to change to prisma-client but for now I still have prisma-client-js.
Using it with no custom path or with ../node_modules/.prisma/client works perfectly fine as usual, however, when setting it to ../generated/prisma/client I get the error:
Error: Dynamic require of "node:fs" is not supported

Why does this happen? I'm more curious than I am in "need of help".

How to reproduce (optional)

No reproduction sorry!

Expected behavior (optional)

I would expect it to not throw this error just because the path changed :)

Information about Prisma Schema, Client Queries and Environment (optional)

• OS: MacOs
• Database: Postgres
• Node.js version: 22.14.0
• Prisma: 6.6.0

Hi @AlvesJorge!

Can you please confirm if you are observing the same behaviour on Prisma 6.7.0 version as well? If yes, can you provide a minimal reproduction of the issue so that we can investigate?

[AlvesJorge]

Hi @nurul3101!
Yes the issue persists!
See @SupertigerDev comment for the minimal reproduction!

[SupertigerDev]

Heres a minimal example:
https://github.com/SupertigerDev/prisma-fs-error-minimal

run these commands

pnpm prisma generate
pnpm dev

im assuming its happening because bundlers are trying to bundle the generated files as well. not sure how to fix it.

@nurul3101 sorry, just want to make sure that you've noticed my reply

[AlvesJorge]

Thank you @SupertigerDev, I can confirm that it is also still happening in 6.7.0 for me, and that your minimal reproduction configuration and error is the same as in my project :)

[nurul3101]

I can confirm the same behaviour. I was able to reproduce the behaviour with your repository.
Removing the custom output path fixed the issue.

Do you mind creating a GitHub Issue so that I can share it with our team internally?

Thanks for the reproduction 🙏
