This Meteor server side code tries to remove the property abc from a document in the users collection but it does not remove it when I check on the mongodb console.
What am I doing wrong? Thanks
Meteor.users.update({_id: userId}, {$unset: {abc: ""}});
I think that what you want to do is:
Meteor.users.update({_id: userId}, {$unset: {abc: 1}});
I agree that the syntax is confusing: 1
actually stands for true
