What steps should I take to resolve the issue of 'unable to locate the name 'OktaAuthService' error?

I am currently trying to incorporate authentication into an Angular application using Okta. I have carefully followed the step-by-step instructions provided in the documentation at this link: . However, I am encountering an error when attempting to start the server. Can someone please assist me with this issue?

export class AppComponent {
 title = 'okta';
  isAuthenticated: boolean;

    constructor(public oktaAuth: OktaAuthService, public router: Router) {
        // Subscribe to authentication state changes
        this.oktaAuth.$authenticationState.subscribe(
            (isAuthenticated: boolean)  => this.isAuthenticated = isAuthenticated
        );
    }

    async ngOnInit() {
        // Get the authentication state for immediate use
        this.isAuthenticated = await this.oktaAuth.isAuthenticated();
    }

! console error

console error

Answer №1

Don't forget to include the necessary imports in your service and component files when injecting services. Even if you've already imported the Okta module in your module ts file, you still need to import the service into the component. Additionally, make sure to import the Router to enable injection (as shown in the screenshot).

import { Router } from '@angular/router';
import { OktaAuthService } from '@okta/okta-angular';

Answer №2

The issue arose due to a conflict between the Angular and Okta versions; I resolved it by downgrading the Okta version as follows:

"@okta/okta-angular": "^3.2.2", "@okta/okta-signin-widget": "^5.10.1",

After updating these two versions, simply use npm install to integrate them into your project
