Meteor collection.insert callback issues

According to the Meteor documentation.... `collection.insert(doc, [callback])` callback Function Optional. If present, called with an error object as the first argument and the _id as the second. ...then later down... On the server, if you don't provide a callback, then insert blocks until the database acknowledges the write, or throws an exception if something went wrong. If you do provide a callback, insert returns immediately. Once the insert completes (or fails), the callback is called with error and result arguments, same as for methods. Which is it, error and _id or error and result? I do have Meteor.methods that are firing their callbacks correctly with error, result available to the scope. I just can't get the callback to work correctly on a collection.insert(doc, [callback]) Either way I can't get my callback to register anything? ``` function insertPost(args) { this.unblock; if(args) { post_text = args.text.slice(0,140); var ts = Date.now(); Posts.insert({ post: post_text, created: ts }, function(error, _id){ // or try function(error, result) and still get nothing // console.log('result: ' + result); console.log('error: ' + error); console.log('_id: ' + _id); //this._id doesn't work either }); } return; } ``` What am I doing wrong? I have been up since 2 am coding...6 pm my time zone...I am blurry, so I might (probably) be missing something quite obvious. Cheers Steeve
