NestJS passport validate with more options other than user and password

Question

I'm trying to prevent users of type "member" from accessing a dashboard. This dashboard shares the same authentication endpoint as the main site. In the POST request to the /login endpoint I'm trying to pass another paramater env="dashboard so that I can tell then return a 400 if the user is a "member" instead of an "admin".

The problem is that this parameter gets stripped out when it reaches the validate() callback in the local strategy. So as far as I can tell it looks like it only expects a username and password. Is there a way to achieve this whilst still keeping the LocalStrategy with the validate?

local.strategy.ts

@Injectable()
export class LocalStrategy extends PassportStrategy(Strategy, 'local') {
  constructor(private authService: AuthService) {
    super({
      usernameField: 'email',
      environment: 'environment',
    });
  }
  async validate(
    email: string,
    password: string,
    environment: string 
//this environment doesn't make it to the getAuthenticatedUser method despite being on
// the request object 
  ): Promise<User> {
    return this.authService.getAuthenticatedUser(email, password, environment);
  }
}

I have tried doing like suggested in this SO question and add it to the super() but still get the same result and when I log the value of environment I get: [Function: verified]

The providers in the auth.module.ts look like this:

providers: [
    AuthService,
    LocalStrategy,
    JwtStrategy,
    ApiKeyStrategy,
    AdminApiKeyStrategy,
  ],

Is there anything I'm missing or is it possible at all to achieve what I'm trying?
