Template Map Field

Hello.

Using this page: https://www.advancedcustomfields.com/resources/google-map/
I’m trying to show the map from the custom field created in a custom post type.

I added my Google API key using method 1 in my functions file. I added this new key in my maps console to an existing project with all APIs enabled and connected to a billing account.

In the back end, the map shows and I can enter and address and get the pinpoint just fine. On the front end, I have a gray square.

My console chrome console shows this error:

InvalidValueError: setCenter: not a LatLng or LatLngLiteral with finite coordinates: in property lat: NaN is not an accepted value

Using the instructions from the link above, I pasted this helper code into my header:

<style type="text/css">
.acf-map {
    width: 100%;
    height: 400px;
    border: #ccc solid 1px;
    margin: 20px 0;
}

// Fixes potential theme css conflict.
.acf-map img {
   max-width: inherit !important;
}
</style>
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY"></script>
<script type="text/javascript">
(function( $ ) {

/**

 *
 * @date    22/10/19
 * @since   5.8.6

 * @return  object The map instance.
 */
function initMap( $el ) {

    // Find marker elements within map.
    var $markers = $el.find('.marker');

    // Create gerenic map.
    var mapArgs = {
        zoom        : $el.data('zoom') || 16,
        mapTypeId   : google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map( $el[0], mapArgs );

    // Add markers.
    map.markers = [];
    $markers.each(function(){
        initMarker( $(this), map );
    });

    // Center map based on markers.
    centerMap( map );

    // Return map instance.
    return map;
}

/**

function initMarker( $marker, map ) {

    // Get position from marker.
    var lat = $marker.data('lat');
    var lng = $marker.data('lng');
    var latLng = {
        lat: parseFloat( lat ),
        lng: parseFloat( lng )
    };

    // Create marker instance.
    var marker = new google.maps.Marker({
        position : latLng,
        map: map
    });

    // Append to reference for later use.
    map.markers.push( marker );

    // If marker contains HTML, add it to an infoWindow.
    if( $marker.html() ){

        // Create info window.
        var infowindow = new google.maps.InfoWindow({
            content: $marker.html()
        });

        // Show info window when marker is clicked.
        google.maps.event.addListener(marker, 'click', function() {
            infowindow.open( map, marker );
        });
    }
}

/**

 *
 * @date    22/10/19

 * @return  void
 */
function centerMap( map ) {

    // Create map boundaries from all map markers.
    var bounds = new google.maps.LatLngBounds();
    map.markers.forEach(function( marker ){
        bounds.extend({
            lat: marker.position.lat(),
            lng: marker.position.lng()
        });
    });

    // Case: Single marker.
    if( map.markers.length == 1 ){
        map.setCenter( bounds.getCenter() );

    // Case: Multiple markers.
    } else{
        map.fitBounds( bounds );
    }
}

// Render maps on page load.
$(document).ready(function(){
    $('.acf-map').each(function(){
        var map = initMap( $(this) );
    });
});

})(jQuery);
</script>

And I added this code to show the map into my template:

<?php 
$location = get_field('location');
if( $location ): ?>
    <div class="acf-map" data-zoom="16">
        <div class="marker" data-lat="<?php echo esc_attr($location['lat']); ?>" data-lng="<?php echo esc_attr($location['lng']); ?>"></div>
    </div>
<?php endif; ?>

The actual field name is ‘address’ so I have tried a bunch of variations to no avail. I keep getting the same error in my console, the lat and long is not coming through. Any ideas?
