startSignalRHub(hub) produces @ngrx/signalr/error + double @ngrx/signalr/disconnected

Hi!

Thanks for that great work.

I have a problem with action startSignalRHub(hub).

When I call startSignalR(hub), it dispatch 3 actions:

@ngrx/signalr/error @ngrx/signalr/disconnected @ngrx/signalr/disconnected

Any idea?

Thanks!

Hi @GeorgBreithaupt

I am not aware of this issue. In order to fix this issue, is it possible for you to provide a reproduction repository?

Sorry, it was described wrong: it's not startSignalRHub but stopSignalRHub. Then always comes

• signalrError
• signalrDisconnected
• signalrDisconnected

Thank you!

I ran into same issue. On connection close there is an error populated this._connection.onclose((error) => { this._errorSubject.next(error); this._stateSubject.next(disconnected); }); and the error subscription const errorSubscription = this._errorSubject.subscribe(() => { observer.error(new Error('The connection has been closed.')); }); in 'on' function throws an error before the observer.complete(); on line 108.

Maybe it's about the order of this events?

Hi @Odonno,

First, thank you for the job you have been doing for this lib.

We just encountered the same issue today, when calling stopSignalRHub, it raises the error "The connection has been close".

Is it an issue that will be addressed soon?

Many thanks
