.NET最小API BadRequest响应不返回正文

app.MapPost($"{root}/v1/AuthenticateUser"
    , async Task<Results<Ok<GetTokenForResponse>, BadRequest<ErrorModel>>> 
    (HttpContext httpContext, IMediator mediator, AuthenticateBody body) =>
{
    var response = await mediator.Send(new AuthenticateUserHandler.Request(httpContext, body.UserName, body.Password));
    if (response.IsSuccessful)
        return TypedResults.Ok(response.Result);
    return TypedResults.BadRequest(response.Error);
})
.WithTags(root);

I am currently running on .NET 7
I am not finding any clues as to why the BadRequest method will NOT return the body
Results.BadRequest Method on MS Docs

似乎这应该返回在GET GO中定义的任何对象.但出于某种原因，事实并非如此.100

public record BaseResponse<T>
{
    public HttpContext? HttpContext { get; set; }
    public bool IsSuccessful => Error is null && Result is not null;
    public ErrorModel? Error { get; set; }
    public T? Result { get; set; }
}

在本例中，T属于一个名为GetTokenFor_Response的类.Ok路径返回有效的正文.BadRequest并非如此.

NOTE: Adding screenshot of Response object coming back from Mediatr:

注2: 问题在Github点开始.

NOTE 3: Changed the Error object like this and it now works. The error was not in the BadRequest method per se. It was a record that did not have public getters? I think?
