How to get networkError details while loading hls stream

While loading a hls stream to the player, sometimes wowza stream returns 403. I tried subscribing to error event but it doesn’t throw any event. How do I intercept network errors returned by wowza.

this.vgAPI.getDefaultMedia()
            .subscriptions
            .error
            .subscribe( (error) => {
            console.log(error);
        });

I checked out hls.js docs, it contains events for network errors https://github.com/video-dev/hls.js/blob/master/docs/API.md#fifth-step-error-handling

Based on this i tried to edit node_modules/videogular2/src/streaming/vg-hls.js and added an networkError check which seems to fire every time wowza returns an error.

// It's a HLS source
        if (this.vgHls && this.vgHls.indexOf('.m3u8') > -1 && Hls.isSupported()) {
            var video = this.ref.nativeElement;
            this.hls = new Hls(this.config);
            this.hls.loadSource(this.vgHls);
            this.hls.attachMedia(video);
            // Error Checking
            this.hls.on(Hls.Events.ERROR, function (event, data) {
                if ( data.type === 'networkError') {
                    console.log('network error encountered');
                }
            });
        }

Is there any event which handles http Error in vgAPI or how can we bind hls.js error events with videogular2 events. Sorry, if i missed out something already mentioned in the docs for this. Thanks!

Sorry if i up this issues,but for bypass https://github.com/videogular/videogular2/issues/726 (when there are errors in hls stream, buffer ring doesnt vanish and error in promise in console )

I try to add

@ViewChild(VgHLS) vgHls: VgHLS;


this.vgHls.hls.on(Hls.Events.ERROR, () =>  {
            console.log('error');
     }); 

but i’ve got

ERROR TypeError: Cannot read property 'on' of undefined
    at StreamingPlayerComponent.push../src/app/streaming-player/streaming-player.component.ts.StreamingPlayerComponent.onPlayerReady

I also have this problem. this.vgHls.hls is undefined.
