PWA fails to load

[adale]

I have a VL Web page built out and working well.
Tried to turn on PWA feature by changing the Offline Support from None to Web App Manifest / Service Worker like I did for a small sample test web page. Compiled and checked in.
The web page now will not load, with this error listed in the Chrome dev console:

Uncaught (in promise) TypeError: Failed to execute 'Cache' on 'addAll': Request failed p1mmain.sw.js:1

I am not familiar enough with the javascript to know what this error is trying to tell me what is wrong.

Anyone have some insights on what I need to correct with my VL Web page in order for it to work as a PWA?

Notes:
The server is set for HTTPS.
I believe I have the two image files loaded in the correct directory (at least I am not getting or seeing a 404 error on the image file names).
I left the cache defaults alone as they are all listed in the Derived App Cache Entries. Meaning I have not gone in and done any changes or edits as to where the app should look for cached items.

Not a real clear answer, but EPC150040 has resolved the non loading of this VL Web app with off line support (PWA).
There are still some issues to work out, but at least now it loads and can function.

PWA woes continue...
EPC150040 had resolved the initial issue of the web app not loading with the following error:
"Uncaught (in promise) TypeError: kx2main.sw.js:1 Failed to execute 'addAll' on 'Cache': Request failed"

All was good, until we discovered that the epc 150040 "broke" the icon feature. Instead of using your selected icon, it would only use or display the Lansa icon.

Hotfix ECP150040HF_210910 was sent to correct this issue. And it did for existing applications (pages) that had been previously set for Offline Support (PWA). The problem is that for any new applications, we are back to the previous error "uncaught. . .".

Now back to developers to try and get a resolution, but no idea how long that will be.
