Hello,

I'm testing the AddMapToBlazorPage example on Blazor Interactive Server 8.0 and I'm getting the following error:

Any ideas, please?

Hello sir,

The AddMapToBlazorPage project uses the Map control for which we have not updated and will not be supported due to some design mistakes. The RealTimeMap control is supported and continuously updated. I checked this control and it works correctly for Blazor Server App project and .NET 8. Do you have more information? For example: how do you run the project? It seems that it cannot find the addresses of the internal files...

Hmm, I tried to create a clean new project, just to be sure the issue is not related to my existing code or settings and, strangely enough, I am getting a different error now:

Hi! For anyone having this issue, I was having this exact error with the basic setup:

_Imports.razor :

@using LeafletForBlazor

My page component :

<RealTimeMap width="600px"
             height="600px"
             Parameters="@parameters">
</RealTimeMap>

@code {
    //map initialization parameters
    RealTimeMap.LoadParameters parameters = new RealTimeMap.LoadParameters()  //general map settings
        {
            location = new RealTimeMap.Location()
            {
                latitude = 44.4501715,
                longitude = 26.1107672,
            },
            zoomLevel = 18
        };
}

The error went away when I put the RealTimeMap component in a div:

<div>
    <RealTimeMap width="600px"
                 height="600px"
                 Parameters="@parameters"></RealTimeMap>
</div>

@code {
    //map initialization parameters
    RealTimeMap.LoadParameters parameters = new RealTimeMap.LoadParameters()  //general map settings
        {
            location = new RealTimeMap.Location()
            {
                latitude = 44.4501715,
                longitude = 26.1107672,
            },
            zoomLevel = 18
        };
}

This workaround is probably a good hint to figure out what's causing the issue.
