[Bug] Read Blazor Webview unhandled exceptions on iOS/Android

[blazorin]

I have some errors inside my Blazor application that end up with a Blazor unhandled exception.
I'm running my Maui Blazor project on iOS 14.5 Xcode 13.0 and can't find any way neither in the debug window I can get to read those messages.

Is there any way to read them or something I can do with the ILogger service?

any update on this?

Hello @3dsx, just wondering if you're still running into this issue. If so, could you kindly provide a minimal, public, github repository which reproduces this issue.

Hey @3dsx, thanks for pointing this out. Great news, it's already possible to access the debug window to read the messages:

iOS

Steps:

1. Open Safari (MacOS app not in simulator)
2. Preferences > Advanced > Show Develop menu in menu bar
3. Run your Blazor dotnet MAUI app webview in the simulator
4. Go back to desktop Safari, Develop > Simulator > 0.0.0.0. If multiple 0.0.0.0 are shown select the one that highlights the webview (makes blue)
5. Web inspector pops up for the iOS simulator webview. Visit the Console tab to see the messages.

Android

Steps:

1. Start emulator and navigate to your Blazor dotnet MAUI app webview
2. Open Edge / Chrome
3. Go to chrome://inspect/#devices, you should see
   
4. Select inspect to pop open DevTools. Visit the Console tab to see the messages.

@guardrex could we please get this documented somewhere? I feel like this may be a common issue and don't know if this GitHub issue will offer enough discoverability.

@TanayParikh I've captured more details from this issue in #4441 as there are several issues around exceptions that are overlapping with each other.

Thanks @javiercn, I'm going to close this issue out in favor of #4441.
