[Question]: Getting null on checkAuthIncludingServer() while using it on auth guard in Angular

[frk93]

What Version of the library are you using?
15.0.2

Question
There are some cases where I got null from checkAuthIncludingServer() function. I am using Angular 15. I am using the checkAuthIncludingServer() function in my guard ( canActivate ) and it hits the function every time I change the pages where I have this guard in place. I noticed when I do it fast or when there is token change I sometimes got null response from the function. I am not sure what causing it, but if someone has more detailed explanation I would appreciate that.

What I am thinking at this point that, while doing it fast and when it ask the authority get a new token and if I still moving through pages of my web application then it fails and unable to retrieve it at that point in time.

My config

@NgModule({
  imports: [
    AuthModule.forRoot({
      config: {
        authority: environment.authConfig.authority,
        redirectUrl: window.location.origin,
        postLogoutRedirectUri: window.location.origin + '/sign-in',
        clientId: environment.authConfig.clientId,
        scope: environment.authConfig.scope,
        responseType: environment.authConfig.responseType,
        unauthorizedRoute: '/sign-in',
        silentRenew: true,
        useRefreshToken: true,
        startCheckSession: environment.platform === 'pwa',
        renewTimeBeforeTokenExpiresInSeconds: 20,
        secureRoutes: [environment.backendBaseUrl],
        configId: environment.configId,
        //       logLevel: LogLevel.Debug,
        ignoreNonceAfterRefresh: true,
      },
    }),
  ],
  providers: [{ provide: AbstractSecurityStorage, useClass: AuthStorage }],
  exports: [AuthModule],
})
export class AuthConfigModule {}

How I solved it at the moment is doing a work around like this

// this code runs in my auth guard to check for auth

return await this.zone.run(async () => {
      try {
        let result: LoginResponse;
        result = await firstValueFrom(this.oidcSecurityService.checkAuthIncludingServer());
        // Workaround 
        if (result === null) {
          return await firstValueFrom(
            this.oidcSecurityService.isAuthenticated$.pipe(
              take(1),
              map((isAuthenticated) => isAuthenticated.isAuthenticated)
            )
          );
        }

        if (result?.isAuthenticated) {
          return true;
        }
        if (result?.errorMessage) {
          this.authenticated = false;
        }
      } catch (error) {
        this.authenticated = false;
        return false;
      }
    });

I am open for suggestion and leads to understanding of the problem.
