npm run final generates an error about Cannot find module './config'

[DelphiCoder]

I am interested getting your book to do some JavaScript desktop work. So I downloaded this desktop example, installed it and then ran

npm run final

This generated the following error:

Uncaught Exception:
Error: Cannot find module './config'

I'm using Windows 11 Pro. Is their something that needs to be coded up first that is discussed in the book or is the example broken?

Thank you...
