The library works perfectlyy well on my local but once in production I have the following error:

Unknown application error occurred

I hard coded env variables to be sure it's not this.

This is on a vercel deployment

[Ehesp]

Vercel is basically tree-shaking out unused modules, and this library does a weird way of attaching the sub-modules:

  partsToAdd.forEach(function (k) {
    exports[k] = require('./client/' + clientPath + k.toLowerCase())[k];
  });

[johngerome]

I'm having the same problem

Error: Cannot find module './client/users'
Require stack:
- /var/task/node_modules/node-zendesk/lib/client.js

Using NextJS V13.

Any workaround?

[Ethaan]

I see both tickets where closed, is there a solution for this?

[blakmatrix]

@Ethaan could you test if the latest version https://www.npmjs.com/package/node-zendesk/v/4.0.1 solves this?
