New Firebase failed: First argument must be a valid firebase URL and the path can't contain ".", "#", "$", "[", or "]"

I am using Firebase to check presence, but the console throws up the following error:

New Firebase failed: First argument must be a valid firebase URL and the path can't contain ".", "#", "$", "[", or "]".

the following is the code:

new Firebase("https://123654789.firebaseio.com/123654/.info/connected").on('value', function(connectedSnap) {
  console.log(connectedSnap.val());
  if (connectedSnap.val() === true) {
    alert('I am connected!');
  } else {
    /* we're disconnected! */
    alert('not connected!');
  }
});

The .info/connected path only exists on the top-level of your Firebase data. You cannot access it from child nodes.

So change

new Firebase("https://123654789.firebaseio.com/123654/.info/connected")

To

new Firebase("https://123654789.firebaseio.com/.info/connected")

And the error message will disappear.
