Having the same issue on windows 10; ionic/angular environment is the same as above. App worked just fine with rc3 and 0.0.45 scripts :frowning:

Steps that worked for me:

  1. get the latest 0.0.48 scripts: npm install @ionic/app-scripts@latest --save-dev

  2. after upgrade, following error occurred on first --prod build: [INFO:CONSOLE(73)] "Uncaught Error: Module build failed: TypeError: Cannot set property ā€˜sourcesā€™ of undefined in node_modules@ionic\app-scripts\dist\webpack\loader-impl.js:35:37

  3. I am not concerned about source maps, so I changed a few lines in loader-impl.js, to read as follows:

         //sourceMapObject.sources = [absolutePath];
     if (sourceMapObject && (!sourceMapObject.sourcesContent || sourceMapObject.sourcesContent.length === 0)) {
         sourceMapObject.sourcesContent = [source];
     }

Best luck to you, but in my case I donā€™t understand where is the actual issue, please see following errorā€¦ if you can get idea let me knowā€¦

Got the same problem, any one knows whatā€™s up?

I was suffering through these and it came down to my have a loading controller object that I was trying to dismiss. I removed the call to its dismiss() method and just added an option of having the loading controller remove itself on page changes. That, for me, solved that issue. It took many many hours to work through that and it was only after someone referencing dismissing controllers that I thought about my use of loading controllers - which had worked fine in previous release candidates. No idea if this will help - but hereā€™s hoping it does.

I am having a similar issue and its driving me crazy. Would you mind showing what you did in code? Thank you !

Are your still having issues?

Today I have upgrade my app from RC3 to RC5 and it has same issue, but finally I fixed

Itā€™s because of loading.dismiss();

Change
loading.dismiss();
To
loading.dismiss().catch(() => {});

this will fix runtime error on RC5 hopefully it might work on RC4 as well.

You have to narrow down the information. e.g: if this error appear upon launching your app, it means you have something wrong in your app module. If error appear upon opening some page, it means the error must be on page you try to open.

You also didnā€™t mention what version you were before upgrading to RC.4

Edit :
I didnā€™t see your last post :smile: it appears you have solve it already :stuck_out_tongue_closed_eyes:
