I am currently trying to deploy an AWS lambda function using serverless. I can get the function to deploy correctly and respond if I don't include any external modules, however as soon as I attempt to include dynogels and Joi:
const dynogels = require("dynogels");
const Joi = require("@hapi/joi");
the serverless deploy command will not get past "packing external modules"
The full output when not including external modules:
❯ sls deploy
{ addHandler: './addHandler.js' }

The packages are installed. I can't see why this isn't deploying. Is there any way I can see some errors from the deploy? --verbose doesn't seem to provide much extra information. Thanks for your help!
