Cannot find module 'encoding/package.json'

[ryanjwilke]

I noticed that someone else a few months ago was struggling with this issue as well, however it wasn't clear what actually resolved the issue for this person. Do you have any idea why this works and builds fine locally, but the build fails in production with the following error? I'm using Netlify Dev as well so theoretically the environments should be pretty close.

5:58:42 PM: Error: In file "/opt/build/repo/lambda-server/user-create.js": Cannot find module 'encoding/package.json' from '/opt/build/repo/lambda-server'

Here's some evidence of the build failing at vue-cli-template#27

Hey there 👋

I was running into this issue as well. After some digging around, I found a workaround that worked for me! The issue for me is in node-fetch. Hopefully this can help you 😄

TLDR

You should:

• npm install encoding
• add require('encoding'); statements in the function files that use node-fetch

Peep this comment, it helped me tremendously: netlify/zip-it-and-ship-it#67 (comment)

---

A module my project depends on conditionally imports the encoding module, and also does not include encoding in it's own package.json. This resulted in my build (with netlify-lambda build) to succeed, but the zip (with @netlify/zip-it-and-ship-it) to not include encoding, so the import would fail.

One annoying thing is that I had to add encoding to my top-level package, which is my frontend app. Adding encoding only to the package.json in my functions folder still fails, probably because that's not where zip-it-and-ship-it is looking? Not sure 😕 I'll probably end up giving node-fetch the boot and use a different request client that hopefully doesn't necessitate this workaround!

@ryan-gilb Thank you for the detailed answer. I'll give that a try soon! That sounds like a simple enough way to fix the issue.

HI Guys,

I just ran into this issue.

I fixed it by adding encoding to my package.json. should encoding be part of the this package or of @netlify/plugin-functions-core?

Here is the error in my console.
