node-chartist not working well with webpack (azure-functions-pack)

[danielserrao]

Hi,

I made an Azure Function micro service using Node.js and I'm using node-chartist to generate graphs. Locally is working fine, but when deploying to development environment, it is executed a script that executes azure-functions-pack and generate a bundle with the service code and all the required npm modules and it seems that for some reason the function generate changes from function to an empty object. In my code I have this:

generate = require('node-chartist')
...
return generate('line', options, data).then((string)=>{
...
});

When using node-chartist I get on the first request the following error in my azure logs:

System.Exception : Error: Cannot find module "." at webpackMissingModule

Locally if I make console.log(typeof generate); I have a function, but if I do the same in development I get an empty object {}.

My node-chartist version is 3.10.10. Thanks for any help.

Locally, if you delete your node_modules, does this work or fail? What's your Node version?
