502 Bad Gatway with Multiple Functions

For the life of me, I cannot get more than one function to work …

In my functions folder, I have 4 JS files. Only one of them seems to work, the rest all return 502 bad gateway. Even when I remove all dependencies and logic, they all still fail to run, other than the first one I ever uploaded.

I’m relying on the deploy process to find and use the node_modules from the parent folder. Since that works for one, why not for the others? From the output in the build, it sure looks like that’s what’s happening, but I can’t seem to get any logging to see what’s happening. Can someone help troubleshoot?

Here’s one of them, as an example.

'use strict';

exports.handler = async (event,context) => {

  const response = {
    statusCode: 200,
    body: JSON.stringify(['hello','world']),

  return response;


Here’s the output for it:

HTTP/1.1 502 Bad Gateway

It should be noted that this function DOES RUN at AWS Lambda, so I reasonably sure it’s coded properly.

@johncokos, based on your functions dashboard, the ftest function was never deployed. If your function is not deploying, you can see three different ways on how to deploy a function on this function deploy example repo.
