ACF Google Maps field not rendering

Question

I am trying to use a google maps field from ACF in my site. I have an api key and am using the example code. I can see the block element on the page but there is not content.

I am getting the following error

google-maps.js:24 Uncaught ReferenceError: google is not defined
at render_map (google-maps.js:24)
at HTMLDivElement.<anonymous> (google-maps.js:151)
at Function.each (jquery.min.js?ver=2.1.0:2)

at Function.ready (jquery.min.js?ver=2.1.0:2)
at HTMLDocument.I (jquery.min.js?ver=2.1.0:2)

I am using the code as found here https://www.advancedcustomfields.com/resources/google-map/ but have replaced the xxx with my own api key here is the code

    /*

function new_map( $el ) {

    // var
    var $markers = $el.find('.marker');


    // vars
    var args = {
        zoom        : 16,
        center      : new google.maps.LatLng(0, 0),

    // create map

        map.fitBounds( bounds );
    }

$(document).ready(function(){

    $('.acf-map').each(function(){

        // create map
        map = new_map( $(this) );

    });

});

})(jQuery);
</script>

I am enqueueing the js as described in this tutorial https://www.aliciaramirez.com/2015/02/advanced-custom-fields-google-maps-tutorial/ I am fairly new to working with js and new to apis so I might have missed something really obvious.

Answer 1

It looks like you are missing <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY"></script> and if it's already in the code, you need to make sure it's in the header (needs to run before your code).
