Error "g is null" with gapi.auth.authorize()

[P THE AWESOME]

I was following the instructions on the Google Developers Guide at How to use CORS to access Google APIs, but I got an error "g is null" when running gapi.auth.authorize().

My relevant HTML code:

<script src="https://apis.google.com/js/api.js" type="text/javascript"></script>

Relevant JavaScript (this is inside of an AngularJS runBlock, but that should have no affect on it):

gapi.load('auth', function() {
  gapi.auth.authorize({
    client_id: 'MYAPIKEY',       // I substituted my API key here
    immediate: false,
    response_type: 'token'
  }, function(access_token) {
    console.debug(access_token);
  });
});

The full error:

Error: g is null
