Hello,

I have this error when I call the initImplicitFlow() method.

Error in initImplicitFlow TypeError: Cannot read property 'responseType' of null

It’s a new project for test this oidc library. Here my package.json

And my AppComponent

  constructor(private oAuthService: OAuthService) {
    this.oAuthService.oidc = true;
    this.oAuthService.issuer = 'http://localhost:20150/auth/realms/demo-oidc';
    this.oAuthService.redirectUri = window.location.origin + '/index.html';
    this.oAuthService.clientId = 'spa-client';
    this.oAuthService.scope = 'openid profile email';

    this.oAuthService.tokenValidationHandler = new JwksValidationHandler();
    this.oAuthService.loadDiscoveryDocumentAndTryLogin()
      .then(d => {
        console.log('discovery and login OK', d);
      })
      .catch(err => console.log('discovery and login ERROR', err));
  }
  public login(): void {
    this.oAuthService.initImplicitFlow();
  }

  public logout(): void {
    this.oAuthService.logOut();
  }
}

Thanks for your help 😃

Hi,

After some tests, your sample work ;p with the last version (5.0.2). And in my project, I have found that set configs like this.oAuthService.issuer = 'xxxxx' not work. The ‘config’ const file work well with Angular DI or this.oAuthService.configure(config); or like this :

const config = new AuthConfig();
config.issuer = 'http://localhost:20150/auth/realms/demo-spring-oauth2';
config.clientId = 'webclient-app';
config.redirectUri = window.location.origin + '/index.html';
config.scope = 'openid profile email';

this.oAuthService.configure(config);

Here in oauth-service.ts, when I try to configure the library with

this.oAuthService.issuer = 'http://localhost:20150/auth/realms/demo-spring-oauth2';
this.oAuthService.clientId = 'webclient-app';
this.oAuthService.redirectUri = window.location.origin + '/index.html';
this.oAuthService.scope = 'openid profile email';

this.config is null

So I think that I must use this.oAuthService.configure(config) with new AuthConfig() object.

Sorry for the late answer 😕 (UTC-10) Thanks for your help 😄

Looking back, I think we can close this issue as OP posted their solution, and some other issues and PRs handle the rest. Let us know if it should be reopened!
