如何在 Twilio Functions 中使用自定义模块？

Question

I was looking for a way to simplify and extract some of the code into a custom common.js module to make my Twilio function more readable.

I was expecting the serverless api to take the custom js file automatically and let me require it where I wanted it, but after deploying, it cant be found.

Is there a proper way if any, to do something like:

const utils = require('./libs/utils.js');
exports.handler = async function(context, event, callback) {
    ...
    utils.do_this();

Trying this brings me to:

{"Message":"Cannot find module './libs/utils.js'\nRequire stack:\n- /var/task/handlers/ZN5be18c53f5acf0299a224607fdeccedb.js\n- /var/task/node_modules/runtime-handler/index.js\n- /var/task/runtime-handler.js\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js","name":"Error","stack":"Error: Cannot find module './libs/utils.js'\nRequire stack:\n- /var/task/handlers/ZN5be18c53f5acf0299a224607fdeccedb.js\n- /var/task/node_modules/runtime-handler/index.js\n- /var/task/runtime-handler.js\n- /...

Swimming deep in Twilio's doc swamp, I noticed there is a hint on how to do this .

Basically you MUST

1. Add the .js file as an PRIVATE ASSET <- IMPORTANT! *unprotected wont work! ie if your file name is utils.js , rename it to utils.private.js
2. Get the path of that asset in the following way:

// notice you don't need to write .private.
const path = Runtime.getAssets()['/utils.js'].path; 

3. Require the path inside the handler:

exports.handler = async function(context, event, callback) {
     const path = Runtime.getAssets()['/utils.js'].path; 
     const utils = require(path);
