When Test Sample Of Project I Get These Error At Send Request Api

I Mean

app.MapGet("/Send/DispatchR", (DispatchR.Requests.IMediator dispatchR, CancellationToken cancellationToken)
        => dispatchR.Send(new DispatchRSample.Ping(), cancellationToken))
    .WithName("SendInDispatchRWithPipeline");

Other Method Not Have Any Problem
