Cannot load GeoJSON when deploying on IIS

[RaHorusFreak]

Hello team, it's me again. My Blazor Server project works ok when debugging on VS. But as soon as I release it into IIS, the map only loads the core layer, and not the GeoJSON i am loading as auxiliary data. This is the code i'm using for it:

protected override async Task OnInitializedAsync()
{
    editContext = new EditContext(search);
    if(WithDocapescaPolygons)
    {
        try
        {
            isLoading = true;
            var response = await mappingService.GetMapGeoJSON();
            if(response.Status == ReturnStatus.Success)
            {
                geoJSON = response.Result!;
                needsPostRender = true;
            }
            else
            {
                toastService.ShowError(response.Error!);
            }
        }
        catch(Exception e)
        {
            toastService.ShowError(e.Message);
        }
        finally
        {
            isLoading = false;
            StateHasChanged();
        }
    }
}

protected override async Task OnAfterRenderAsync(bool firstRender)
{
    if(needsPostRender && _map is not null)
    {
        needsPostRender = false;
        try
        {
            await LoadGeoJSON();
        }
        catch(Exception e)
        {
            toastService.ShowError(e.Message);
        }
        finally
        {
            StateHasChanged();
        }
    }
    await base.OnAfterRenderAsync(firstRender);
}

private async Task LoadGeoJSON()
{
    var layer = _map.LayersList.FirstOrDefault(l => l.Id.Equals(layerId));
    if(layer is not null)
        await _map.RemoveLayer(layer);
    if(geoJSON is not null)
    {
        await _map.AddLayer(layer = new Layer()
            {
                Id = layerId,
                LayerType = LayerType.Vector,
                SourceType = SourceType.VectorGeoJson,
                Projection = geoJSON.Authority,
                Data = geoJSON.Content,
                StyleCallback = GetShapeStyle,
                RaiseShapeEvents = true
            });
        await _map.SetZoomToExtent(layer);
    }
}

LoadGeoJSON() method runs without any exception, the properties geoJSON.Authority and geoJSON.Content (exported from GDAL/OGR) are ok, just as when I debug on VS, but after calling await _map.AddLayer there's no new layer added (just when I release with IIS). The console doesn't show any error, so I'm lost at that point. Any ideas about what could be the problem?

Thanks in advanced. Best regards.
