Meteor Restivus: Error Meteor.userId can only be invoked in method calls

Question

I am trying to use Restivus to expose a get route to return a specific document by its serial number.

Basic code:

// lib/router.js
Router.onBeforeAction(requireLogin, {
  except: ['auth', 'api']
});

// server/restivus.js
Meteor.startup(function() {
  Restivus.configure({
    useAuth: false,
    prettyJson: true
  });
});

// lib/collection/schedule.js

if (Meteor.isServer) {
  Restivus.addRoute('schedules/:serial', {authRequired: false}, {
    get: function() {
      var schedule = Schedules.findOne({collector: this.urlParams.serial});
      if (schedule) {
        return {status: 'success', data: schedule};
      }
    }
  });
}

Complete log error:

curl -X GET http://localhost:3000/api/schedules/00000020

Error: Meteor.userId can only be invoked in method calls. Use this.userId in publish functions.

Answer 1

I solved adding !Meteor.isServer at hook onBeforeAction:

var requireLogin = function() {
  if (!Meteor.isServer && !Meteor.userId() && !Meteor.loggingIn()) {
    this.redirect('auth');
  } else {
    this.next();
  }
};

Router.onBeforeAction(requireLogin, {
  except: ['auth']
});
