Missing callback when calling Google Maps API

The short answer is to specify a callback value. Set the name of the JavaScript function that you would like to trigger once the external API library has finished loading.

https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=FUNCTION_NAME

If you don't actually have a callback function to run immediately after the library loads, you can use Function.prototype as a noop stand-in.
