Getting function.js does not exist error when deploying 1st gen cloud function

Question

I am writing a simple helloWorld function in a node.js(v16) app that I want to deploy using the 1st gen Google Cloud Functions (I want to eventually use GitHub Webhooks to deploy code). I keep getting this error:

Build failed: function.js does not exist; Error ID: 7485c5b6

This is my code:

index.js

const crypto = require('crypto');
const got = require('got');
const url = require('url');

const settings = require('settings.json');

/**
 * Responds to any HTTP request.
 *
 * @param {!express:Request} req HTTP request context.
 * @param {!express:Response} res HTTP response context.
 */
exports.helloWorld = (req, res) => {
  let message = req.query.message || req.body.message || 'Hello World!';
  res.status(200).send(message);
};

package.json

{
  "name": "sample-http",
  "version": "0.0.1",
  "dependencies": {
    "got": "^12.5.2",
    "url": "^0.11.0"
  }
}

settings.json

{
  "secretToken": "webhook_token",
  "accessToken": "github access token",
}

This app folder also contains a package-lock.json file and a folder for node_modules.

What am I missing here? Why do I keep getting the error Build failed: function.js does not exist; Error ID: 7485c5b6?

I have deployed it using the UI using this method: ZIP from Cloud Storage and also tried deploying using this command: gcloud functions deploy helloWorld --runtime nodejs16 --entry-point=index --trigger-http --stage-bucket bucket-name

I was running into this because I was compressing a folder with the files. What I needed to do was to highlight just the files and then select "compress".

Additionally you need to make sure your exported function name matches your entry_point parameter value if you're using Terraform.

google_cloudfunctions_function Terraform

entry_point = "exampleFunctionName"

index.js export

exports.exampleFunctionName = (event, context) => {
