FindPlaceFromQueryRequest isn't correctly serialized

[kimonmeier]

Hello

Im currently implementig the places service and while trying to query for places an exception got triggered. Somehow i can't really solve it. I has something todo with the FindPlaceFromQueryRequest and the LocationBias, which isn't correctly serialiazed. Is there something wrong on my side, configuration wise?

Kind Regards

Code-Example:

@using GoogleMapsComponents
@using GoogleMapsComponents.Maps
@using GoogleMapsComponents.Maps.Places
@inject IJSRuntime JS

<GoogleMap @ref="@_map" OnAfterInit="OnAfterMapInit" Options="@_mapOptions" Id="map"></GoogleMap>
@code {
    private GoogleMap _map = default!;
    private MapOptions _mapOptions = default!;
    private PlacesService placeService = default!;


    private async Task OnAfterMapInit()
    {
        var module = await JS.InvokeAsync<IJSObjectReference>("import", "./Components/Maps/LocationPicker.razor.js");
        await module.InvokeVoidAsync("addCenterMaker");

        this.placeService = await PlacesService.CreateAsync(this._map.JsRuntime, _map.InteropObject);
    }

    protected override void OnInitialized()
    {
        _mapOptions = new MapOptions()
            {
                Zoom = 13,
                Center = new LatLngLiteral()
                {
                    Lat = 13.505892,
                    Lng = 100.8162
                },
                MapTypeId = MapTypeId.Roadmap
            };
    }

    public async Task SearchPlace(string search)
    {
        var response = await this.placeService.FindPlaceFromQuery(new FindPlaceFromQueryRequest()
            {
                Fields = ["name", "geometry"],
                Query = search,
                LocationBias = null
            });

        if (response?.Results?.Geometry?.Location is null)
        {
            return;
        }

        await _map.InteropObject.SetCenter(response.Results.Geometry.Location);

        this.StateHasChanged();
    }

    public async Task SetCenter(double latitude, double longitude)
    {
        await _map.InteropObject.SetCenter(new LatLngLiteral(latitude, longitude));
    }

    public Task<LatLngLiteral> GetCenter()
    {
        return _map.InteropObject.GetCenter();
    }
}

LocationBias is only class which implements OneOfBase. Could be that functionality was lost after migration to System.Text.Json
Second probably it is workaround (solution) to write like this

public OneOf<LatLngLiteral, string>? LocationBias { get; set; }

Problem that that implements 5 types which i think 3 is max. Which is in OneOfConverterFactory

LocationBias : OneOfBase<LatLngLiteral, LatLngBounds, LatLngBoundsLiteral, Circle, string>

Probably easiest solution would be find which 3 params works in most cases. O harder write serializer for 5. There are examples so probably doable.
Another problem that it is resolved in promise which could couse some testing for right solution (i could be wrong)

Here is my findings. Hard to promise deadline. This is very rare. For sure this year :)
