Expected / Desired Behavior / Question

I am trying to connect to my SharePoint site using node for testing using sp.setup

Observed Behavior

I receive an error Error: Cannot find module '.'

Error: Cannot find module '.'

I followed all steps from here to register and grant access:
https://social.technet.microsoft.com/wiki/contents/articles/52893.sharepoint-framework-introduction-to-test-driven-development-tdd-using-jest-enzyme.aspx

I first encountered the error trying to connect from a unit test.
I then tried to test by removing everything except exactly what I should need to connect and here is my code for that.

import { sp } from "@pnp/sp";
import { SPFetchClient} from "@pnp/nodejs";

sp.setup({
    sp: {
        fetchClientFactory: () => {
            return new SPFetchClient("https://nameredacted.sharepoint.com", "redacted", "");
        },
    },
});

sp.web.select("Title").get().then(w => {
    console.log(`Web Title: ${w.Title}`);
});

Steps to Reproduce

As part of trying to get this to work, I have followed several different examples all with the same result.

Here is a self-contained example that causes the issue for me if I follow the instructions exactly.
https://www.c-sharpcorner.com/article/client-side-development-with-sharepoint-using-nodejs-and-pnp3/

Something strange is going on in SPFetchClient if I return {} instead of SPFetchClient I don't get the Error: Cannot find module '.' instead I get a different error about headers being missing.
