I am currently testing the openstreetmap integration uing syncfusion
Looking at their documentation => https://blazor.syncfusion.com/documentation/maps/providers/openstreetmap

I tryed running this code:

@using Syncfusion.Blazor.Maps

<SfMaps>
    <MapsZoomSettings ZoomFactor="4"></MapsZoomSettings>
    <MapsCenterPosition Latitude="29.394708" Longitude="-94.954653"></MapsCenterPosition>
    <MapsLayers>
        <MapsLayer UrlTemplate="https://tile.openstreetmap.org/level/tileX/tileY.png" TValue="string">
            @* Add marker *@
            <MapsMarkerSettings>
                <MapsMarker Visible="true" Height="25" Width="15" DataSource="Cities" TValue="City">
                </MapsMarker>
            </MapsMarkerSettings>
            @* Add navigation line *@
            <MapsNavigationLines>
                <MapsNavigationLine Visible="true" Color="blue" Angle="0.1" Latitude="new double[]{34.060620, 40.724546}"
                                    Longitude="new double[]{-118.330491,-73.850344}">
                </MapsNavigationLine>
            </MapsNavigationLines>
        </MapsLayer>
    </MapsLayers>
</SfMaps>

@code{
    public class City
    {
        public double Latitude { get; set; }
        public double Longitude { get; set; }
        public string Name { get; set; }
    }
    private List<City> Cities = new List<City> {
        new City { Latitude = 34.060620, Longitude = -118.330491,  Name="California" },
        new City{ Latitude = 40.724546, Longitude = -73.850344,  Name="New York"}
    };
}

This is what they have:

this is what I get:

I do not have any crash report, neither in my Visual Studio, neither in the web console.

Also, trying their second exemple (Enable zooming and panning)
I am not able to zoom or pan the map

Any idea of what I do wrong? Thx
