Why does Google api return an error with status 200?

Question

Google Maps

$.ajax({
            url: 'https://maps.googleapis.com/maps/api/elevation/json?locations=39.7391536,-104.9847034', 
            type: "GET",   
            dataType: 'jsonp',
            cache: false,
                  
        }).then(function(response){                          
                console.log(response);                   
            },
            function(er){
                console.log('error')
                console.log(er)
            });

Returns:
error
Object {readyState: 4, status: 200, statusText: "load"}

Answer 1

well, status 200 is the status of the server response, not logic

Answer 2

JSONP is not supported.
