Http Interceptor

[jtan80813]

Hi. I have a problem in my authentication. I have attached the http interceptor in every request i make. I have a problem in logging in of my application. I am not able to login since i have this error in my code

These are my codes

onSignIn() {
    const formData = {
      email: this.loginForm.get('email').value,
      password: this.loginForm.get('password').value
    };
    if (this.loginForm.valid) {
      this.authService.signinUser(formData)
      .subscribe(
        data => {
          console.log(data);
          this.cookieService.set('auth_token', data.token);
          console.log(data);
        },
        error => {
          console.log(error);
        });
    }
  }

`@Injectable()
export class AuthInterceptor implements HttpInterceptor {
  private authService: AuthService;

  constructor(private injector: Injector, private router: Router, private cookieService: CookieService) {}

    // Get the auth header from the service.
    this.authService = this.injector.get(AuthService);
    const token: string = this.cookieService.get('auth_token');
    const role: string = this.authService.getRole();

Hello,

this seems to be an implementation issue and has nothing to do with any ngx-cookie-service bugs or issues. Therefore, helping you is sadly out of scope for us. However, you can ask the friendly people over at StackOverflow for help. I'm sure someone there will have a tip for you.

Cheers
