Meteor: onUserCreation

Question

I'm very new to Meteor and already have so many headaches.. perhaps anyone can explain the following:

I'm using the Josh Owen entry package for FB, G+, etc login. Eventually I want to add more fields to the user collection. But for now I was just testing and logging to console:

Accounts.onCreateUser(function(options, user) {
    console.log(user);
});

And in console I get the following error:

Answer 1

You have to return user. Example from Meteor docs:

// Support for playing D&D: Roll 3d6 for dexterity
Accounts.onCreateUser(function(options, user) {
  var d6 = function () { return Math.floor(Random.fraction() * 6) + 1; };
  user.dexterity = d6() + d6() + d6();
  // We still want the default hook's 'profile' behavior.
  if (options.profile)
    user.profile = options.profile;
  return user;
});

You can use console.log(user); before return statement.
