Google Map not loading after cookie confirmation

Today I recognized that the google map is not loading after the cookie confirmation. It works a coupleof weeks before.
Cookie Notice Vers. 1.2.45 for WordPress 5.0.2

I use this code in the footer:

<script>
			var geocoder;
			var map;

			var isDraggable = $(document).width() > 768 ? true : false;

			function initialize() {
				geocoder = new google.maps.Geocoder();
					
				var mapOptions = {
					zoom: ,
					disableDefaultUI: false,
					scrollwheel: false,
					panControl: true,
					scaleControl: true,
					draggable: isDraggable,
					mapTypeId: google.maps.MapTypeId.ROADMAP,
					styles: [ { "featureType": "water", "elementType": "geometry", "stylers": [ { "visibility": "on" }, { "color": "#73b0c9" } ] },{ "featureType": "landscape.natural", "stylers": [ { "color": "#e3d5bf" } ] },{ "featureType": "road", "stylers": [ { "color": "#f8f0d9" } ] },{ } ]
				}

				map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
				codeAddress();
			}

			function codeAddress() {
			  var address = "";
			  geocoder.geocode( { 'address': address}, function(results, status) {
				if (status == google.maps.GeocoderStatus.OK) {
					map.setCenter(results[0].geometry.location);
					var iconBase = '/images/';
					var marker = new google.maps.Marker({
				        map: map,
				        icon: iconBase + 'map-icon.png',
				        position: results[0].geometry.location
				    });
				} else {
				  alert('Geocode was not successful for the following reason: ' + status);
				}
			  });
			}

			google.maps.event.addDomListener(window, 'load', initialize);

			</script>

Google Chrome gives me this error message:
Google Maps JavaScript API warning: SignedInNotSupported https://developers.google.com/maps/documentation/javascript/error-messages#signed-in-not-supported

Is it new that a google api is provided also for google map (as well as at google captcha?) ?
And if so, how does the code have to be adjusted?

Thanks a lot and a happy new year.
