Angular 我能把角http拦截器改为500吗？

我有一个http拦截器，它将截获500个错误并向用户显示一个对话框。下面是我的拦截器代码片段：

intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    ....
    return next.handle(request).pipe(catchError(error => {
        // intercept the respons error

        this.handleAuthError(error, request); // pass error to function
        return of(error.error);
    }) as any, finalize(() => {
        ++this.counter;
        this.enableSubmissionButton(this.counter);
    }));
}

private handleAuthError(err: HttpErrorResponse, request: HttpRequest<any>): Observable<HttpEvent<any>> {
    // handle your auth error or rethrow
    let errorMessage: any = '';

    if (err.error instanceof ErrorEvent) {
        errorMessage = `Error: ${err.error.message}`;
    } else {
        errorMessage = `Error Code: ${err.status}\nMessage: ${err.message}`;
        if (err.status === 401 || err.status === 403) {
            this.userAuthService.purgeAuth();
        } else if (err.status === 500 || err.status === 404) {
            this.dialog.open(MessageDialogComponent, {
                disableClose: true,
                data: err.error.Message || `${err.status} ${err.statusText}`,
            });
        }
    }
    return throwError(errorMessage);
}

显然，上面的console.log不会发生，因为http拦截器会处理它。 我可以做些什么来检查（例如）上面的请求是否有500个错误，即使http拦截器已经处理了它。如果在这个请求中有任何这样的错误，我需要运行一些特定的代码

this.subscription.add(
        url.subscribe(data => {
            if (data.Status) {
                // Save was successful.
            } 
        }, err => {
            console.log(err);
        })
    );
