Comment: Anonymous authentication (cookbook/authentication/anonymous.md)

Comment/Problem

I need anonymous login for my project and i followed every step here and on internet. Error i get is: "Invalid authentication information (strategy not allowed in authStrategies)"

I have: authentication.register('anonymous', new AnonymousStrategy()); and i see it in console.log(authentication);

anonymous:
AnonymousStrategy {
name: 'anonymous',
app: [EventEmitter],
authentication: [Circular] } },

but no matter what i try i get that error. Client side i try to: user = await client.authenticate({strategy: 'anonymous', name: credentials.email, email: 'asd', password: '123', room: '1'}); .. and every possible combination i could try.. it will just say that there is no such strategy.

this is my authentication.js:

const { AuthenticationService, JWTStrategy, AuthenticationBaseStrategy  } = require('@feathersjs/authentication');
const { LocalStrategy } = require('@feathersjs/authentication-local');
const { expressOauth } = require('@feathersjs/authentication-oauth');

class AnonymousStrategy extends AuthenticationBaseStrategy {
  async authenticate(authentication, params) {
    return {
      anonymous: true
    }
  }
}

module.exports = app => {
  const authentication = new AuthenticationService(app);

  authentication.register('jwt', new JWTStrategy());
  authentication.register('local', new LocalStrategy());
  authentication.register('anonymous', new AnonymousStrategy());

  app.use('/authentication', authentication);
  app.configure(expressOauth());
}

Also, postman request POST /authenticate { "strategy": "anonymous"} returns: "message": "Invalid authentication information (strategy not allowed in authStrategies)",

System configuration (optional)

You do not need to call app.authenticate with the anonymous strategy. It will be used automatically if no other authentication information is used.
