🐞

- What is the current behavior?

In a rush monorepo with pnpm @prisma/client and .prisma files aren’t included in function node_modules and throw the error:

{
errorType: "Runtime.ImportModuleError",
errorMessage: "Error: Cannot find module '@prisma/client' Require stack: - /var/task/.netlify/functions-internal/next_api_views/next_api_views.js - /var/task/next_api_views.js - /var/runtime/UserFunction.js - /var/runtime/index.js",

}

- If the current behavior is a bug, please provide the steps to reproduce.

• Create a rush monorepo with pnpm as package manager.
• Add a nextjs app with prisma inside of monorepo
• Set next target to experimental-serverless-trace
• Run prisma generate && netlify-cli build && netlify-cli deploy
• Unzip a function that uses prisma from .netlify/functions/ and see that @prisma/client and .prisma are not included in node_modules

If you change the package manager from pnpm to npm then is working as expected.

I created a repository where you can reproduce the issue: https://github.com/abereghici/prisma-next-netlify-rush

- What is the expected behavior? @prisma/client and .prisma files should be included in node_modules when using pnpm.

- Please mention your node.js, and operating system version.

Thank you @abereghici! I think I was able to reproduce the error based on https://github.com/outerlook/netlify-prisma-nexus, I’ll use your repository to verify a fix once we have it.

Yay, sorry but happy to see this issue. I’m getting this too.

If I may add, local netlify dev works perfectly. Only when uploading, the problem arises. In my case, if I try to add --shamefully-hoist to install option, the error displayed complains about lack of nexus-plugin-prisma module.

But while using pnpm monorepo, it ain’t so easy to go back to npm structure
