Why do I keep getting the error trying to load googlemaps?

Question

I am trying to migrate from v2 to v3 in google maps API and I keep getting this error: The Google Maps API server rejected your request. The "sensor" parameter specified in the request must be set to either "true" or "false".

Here is the tutorial I am using: https://developers.google.com/maps/documentation/javascript/tutorial

In the javascript I have changed src to

<script type="text/javascript"
  src="http://maps.googleapis.com/maps/api/js?key=AIzaSyDzGdafsdfdfgoO4cHbfRGL8W23dgfafJKnA&sensor=TRUE">
</script>

but I keep getting the following error: The Google Maps API server rejected your request. The "sensor" parameter specified in the request must be set to either "true" or "false".

What does the error mean and how can I fix it?

Answer 1

Use: sensor=true instead of sensor=TRUE

It is case-sensitive.
