catchError in effects not working

[jmeinlschmidt]

Which @ngneat/effects-* package(s) are the source of the bug?

effects-ng

Is this a regression?

No

Description

Operator catchError in effects is not working and after throwing an error, the effect stops emitting. Please see full example in stackblitz.

public myEffect = this.createEffectFn(($: Observable<string>) =>
  $.pipe(
    tap((no) => console.log('effect invocation', no)),
    map(() => {
      throw new Error('error here');
    }),
    catchError((e) => {
      console.log('catched', e);
      return of();
    })
  )
);

This is related to #34. I think this applies to effect functions as well, see createEffectFn implementation.

I have the same issue, when try to make HTTP request

loadUsers$ = createEffect((actions) =>
        actions.pipe(
            ofType(loadUsers),
            switchMap(() => this.usersService.getAll()),
            catchError((err) => { notifyAboutError(err); return NEVER; }),
            tap(setUserList)
        )
    );

After an error occurs, the effect stops. One possible solution is to refrain from catching errors within the action pipe and instead catch them in the HTTP response stream, as illustrated below:

loadUsers$ = createEffect((actions) =>
        actions.pipe(
            ofType(loadUsers),
            switchMap(() => this.usersService.getAll().pipe(catchError(() => {
                 notifyAboutError(err);
                 return of(null);
            }))),
            tap((result) => {
                if (!result) return;
                setUserList(result);
            })
        )
    );
