I'm using google auth on a web project and I'm trying to understand the property names. The screenshot shows the user object returned by google. I can access the id_token this way:

this.user.Zb.id_token

Why Zb? A year ago it was this:

this.user.wc.id_token

Notice it was wc back then and now my UI code breaks. What am I missing? Why are those property names used? How do I make it so I can access id_token regardless of its parent property name?

This is the UI code:

  async authenticate(): Promise<gapi.auth2.GoogleUser> {
    // Initialize gapi if not done yet
    if (!this.gapiSetup) {
      await this.initGoogleAuth();
    }

    // Resolve or reject signin Promise
    return new Promise(async () => {
      await this.authInstance.signIn().then(
        user => {
          this.user = user;
          console.log('this.user: ', this.user);
          
          this.cookieService.set('jwt', this.user.Zb.id_token, 365); // expires in one year (365 days)
          // this.cookieService.set('jwt', this.user.wc.id_token, 365); // expires in one year (365 days)

          this.owlerApiService.getHooterUsingIdTokenFromProvider()
            .subscribe((data: any) => {
              this.userDto = data;            
            },
            error => {
              console.log('error: ', error);
            });
        },
        error => this.error = error);
    });
  }

  async initGoogleAuth(): Promise<void> {
    // Create a new Promise where the resolve function is the callback passed to gapi.load
    const pload = new Promise((resolve) => {
      gapi.load('auth2', resolve);
    });

    // When the first promise resolves, it means we have gapi loaded and that we can call gapi.init
    return pload.then(async () => {
      // ClientId safe to put here? Looks like it:
      // https://stackoverflow.com/a/62123945/279516
      await gapi.auth2
        .init({ client_id: 'xxx.apps.googleusercontent.com' })
        .then(auth => {
          this.gapiSetup = true;
          this.authInstance = auth;
        });
    });
  }
