Error: Cannot find module '@prisma/client' in netlify functions when using prisma + next + rushjs + pnpm

🐞

- 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.

I spent some time debugging this issue and here are my findings:

Rush with PNPM doesn't install nested dependencies but prisma depends on

"dependencies": {
    "@prisma/engines-version": "2.30.1-2.b8c35d44de987a9691890b3ddf3e2e7effb9bf20"
  }

so, in node_modules of the project we have only "@prisma/client" because is symlinked by pnpm. @prisma/engines-version is not a direct dependency so it lives somewhere in common/temp/node_modules/.pnpm/@prisma+client@2.30.2_prisma@2.30.2/node_modules/@prisma.

getDependenciesForModuleName for @prisma/client fails because

zip-it-and-ship-it/src/node_dependencies/traverse.js

Line 120 in cfec60f

getNestedModules({ modulePath, state, packageJson, pluginsModulesPath }),

cannot find @prisma/engines-version in node_modules of the project and in the end all @prisma dependencies are skipped.

A potential fix is to manually add @prisma/engines-version along with @prisma/client in package.json.

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

I almost created another minimal repro without rush that self contains a SQLite file as database to test.

But I didn't get it to work on Netlify, just locally.
(the problem here is I don't know how to preserve the file for prisma to be able to read)

Anyway, the structure is the same as I get errors, if someone can give any idea to create this self-contained repro that works on netlify online. Or if this is already enough for the team to reproduce the error with a Database of your own online.

Hi @abereghici! Thank you for providing a reproduction repository. It seems like apps/next-app is a symlink, is that intended?

[abereghici]

@netlify-team-account-1 Sorry, there was a misconfiguration. I updated the repository.

[netlify-team-account-1]

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.

Sorry to necro bump but is there a fix for this for regular npm too? I'm running into this and would love a way to debug / a fix potentially?

[Skn0tt]

Not sure what issue you're referring to - if there's already an issue for it in this repository, could you link it? If not, feel free to open one :)

[erlandsona]

Turns out it's likely not this... and more to do with a js module trying to execute an import statement like an mjs module. My b.
