How can i replace retryWhen on this ngrx effect?

I have this code that work as intended:

• i dispatch a signin function
• the effect take data fom action and make http post
• if the error status is 504 i retry the http post
• if it’s all ok -> success action else error action

authSignIn$ = createEffect(() => this.actions$.pipe(
    ofType(authActions.signInStart),
    exhaustMap(action => this.http
      .post<responseModel.SignInResponse>(`${environment.baseUrl}/${authBaseUrl}/${ApiPaths.singIn}`, {
        codF: action.username,
        password: action.password
      })
      .pipe(
        map((response) => authActions.signInSuccess({user: response.accountInfo, token: response.token})),
        catchError((error: HttpErrorResponse) => {
          if (error.status === 504) {
            return throwError(() => error);
          }
          return of(authActions.signInFail({error: error.message}))
        }),
        retryWhen((errors) => errors.pipe(delay(4000), take(4)))
      )
    )
  ));

but on RxJs documentation (https://rxjs.dev/api/operators/retryWhen) the retryWhen operator is tagged as deprecated…
So, how can i modify this code to do the same things but without deprecated operators? What is the replacement for replyWhen (if there’s one)?

>Solution :

The Deprecation Notes (https://rxjs.dev/api/operators/retryWhen) state to use retry with a delay option. retry takes a RetryConfig object, which has following properties: count, delay and resetOnsuccess.

With your code given above you should try this:

retry({ count: 4, delay: 4000 })
