enableJSErrorTracking not working

[krechtern]

Hey, I'm trying to "log" all uncaught JS errors with matomo. I enabled the enableJSErrorTracking option, but no request is made when an error occurs.

provideMatomo(
      {
        mode: MatomoInitializationMode.AUTO_DEFERRED,
        disabled: !environment.matomoTrackingEnabled,
        enableJSErrorTracking: true,
      },
      withRouter({ exclude: ['/login'] })
    ),

I tried to debug the matomo.js file and see if the window.onerror function is called. It seems like this is not even happening. The normal tracking is working fine. Does anybody has an idea what could be wrong?

We are currently on Angular version 16.2.12 and are using version 5.0.4 of this library.

Note: I tried to throw and error and also to force an error with calling an non existing function.

Hi @krechtern

I can't manage to reproduce your issue. Could you please provide a repro ?

How exactly are you testing that behavior? Can you provide example?

Hey, I sadly can't provide the repo where I stumbled upon this problem. I will see if I can setup a small example repo and check if I can reproduce it there.

To test the error catching I threw an error in our AppComponent in ngOnInit. But I also noticed that window.onerror is also not working if I define the function myself. I was only able to catch all uncaught errors with providing a custom ErrorHandler.
