html-nodejs example: document undefined error in Windows system, but same works in macOS

[ravitejaavv]

Able to run this html project and render the home page locally in mac OS
https://github.com/markdoc/docs/tree/main/examples/html-nodejs

But same is not working in windows 10 & 11.
Local host is always showing "not found" error (404).

In Windows, always the control goes to document not found condition and showing 404 error. We tried almost all latest nodejs versions and still the problem is same.

const path = req.params[0];
const document = contentManifest[path];

if (!document) {
return res.sendStatus(404);
}

Can anyone help me on this issue?
