Service worker is not working in offline mode when angular project is deployed on IIS

Question

I have created an angular (angular 7) application and then added ng add @angular/pwa angular PWA library to it. Now after building it using ng build --prod and then serving the application to localhost:8080 via node's http-server, my application is running fine in offline mode in localhost.

But when i build the same application using ng build --prod --base-href /myProject/ to deploy on IIS, application is working fine but when switch to offline mode using chrome's developer tool, i am getting error HTTP Error 504.

Please suggest what is causing this strange behavior and how to fix it.

you can give it a try by omitting "--base-href /myProject/" while building

After omtting this command, i won't be able to deploy the project in a sub-folder in IIS. – vndpal Dec 17 '19 at 12:33
outcome of this command will be "dist" folder in root, simply copy paste the content of it to your IIS folder, this should work, – er-Chaan Dec 18 '19 at 08:47
I have tried it, but no luck. I suspect it has something to do the way angular application is build. – vndpal Dec 18 '19 at 09:42
try alter your index.html file ```--base-href=./ ``` – er-Chaan Dec 18 '19 at 10:45
