Error when styling map

[churro90]

Im declaring a custom style to my map as follows:

 var mapProp = {
      zoom: 14,
      center: myLatLng,      
      styles: [{"featureType":"landscape.natural","elementType":"geometry.fill","stylers":[{"visibility":"on"},{"color":"#e0efef"}]},{"featureType":"poi","elementType":"geometry.fill","stylers":[{"visibility":"on"},{"hue":"#1900ff"},{"color":"#c0e8e8"}]},{"featureType":"road","elementType":"geometry","stylers":[{"lightness":100},{"visibility":"simplified"}]},{"featureType":"road","elementType":"labels","stylers":[{"visibility":"off"}]},{"featureType":"transit.line","elementType":"geometry","stylers":[{"visibility":"on"},{"lightness":700}]},{"featureType":"water","elementType":"all","stylers":[{"color":"#7dcdcd"}]}]

    }

    this.map = new google.maps.Map(this.gmapElement.nativeElement, mapProp);

The map works correctly and displays the style but when compiling I'm getting the following error
ERROR in src/app/component/home/home.component.ts(52,68): error TS2345: Argument of type '{ zoom: number; center: LatLng; styles: ({ "featureType": string; "elementType": string; "stylers...' is not assignable to parameter of type 'MapOptions'.

Any ideas as why this is happening?

Can you check that you are following correct styling as below?

It is correct. Im implementing the following map: https://snazzymaps.com/style/61/blue-essence

When I go to the error details i'm getting some undefined parameterers:

(local var) mapProp: { zoom: number; center: google.maps.LatLng; styles: ({ "featureType": string; "elementType": string; "stylers": ({ "visibility": string; "hue"?: undefined; "color"?: undefined; } | { "hue": string; "visibility"?: undefined; "color"?: undefined; } | { "color": string; "visibility"?: undefined; "hue"?: undefined; })[]; } | { "featureType": string; "elementType": string; "stylers": ({ "lightness": number; "visibility"?: undefined; } | { "visibility": string; "lightness"?: undefined; })[]; })[];
