Why refs to local URLs in build for PWAs?

When I check my access weblogs for an Ionic/Cordova web app, released online. I see that visitors are requesting sources with URLs like: https://mydomain.com/home/windowsuser/Desktop/ionicapps/app1/www/build/main.js.map

Why are there references to my Windows local development environment in the final prod release build? The app is working online without any errors in Chrome dev console. The URL is actually a mix of local URL, still using https://mydomain.com/ though, like if it’s a relative link.

Did you check the sourcecode of your app for these URLs?
How did you build the app you uploaded?

What is your ionic info output?
