core3.1使用异常中间件捕获400等错误，显示多个异常提示，怎样只显示自己定义的

悬赏园豆：10 [待解决问题]

postman 提示界面如图：上面是自带提示，下面是我自定义。

 {
"type": "https://tools.ietf.org/html/rfc7231#section-6.5.1",
"title": "One or more validation errors occurred.",
"status": 400,
"traceId": "|e83645f6-45a222f9ff0ab1de.",
"errors": {
    "$.UserDesc": [
        "Expected depth to be zero at the end of the JSON payload. There is an open JSON object or array that should be closed. Path: $.UserDesc | LineNumber: 6 | BytePositionInLine: 0."
    ]
}

}

{
"code": 400,
"msg": "执行方法中抛出异常错误",
"data": "url:/AteUser"
}

程序输出方式：await context.Response.WriteAsync(json);

问题补充：

执行方式：

  public async Task Invoke(HttpContext context)
       {
        try
        {
            await _next(context);
        }
        catch (Exception ex)
        {
            if (ex is ServiceException serviceException)
            {
                await HandleExceptionAsync(context, serviceException.LogSn, ex.Message);
            }
        }
        finally
        {
            if (context.Response.StatusCode >= 400&& context.Response.StatusCode < 599)
            {
                await HandleExceptionAsync(context, context.Response.StatusCode, "");
            }

        }
    }

catch可正常抛出异常，finaly则会抛出两个对象异常

输出方式：

     try
        {
            context.Response.Clear();
        }
        catch (Exception ex)
        {
            //throw ex;
        }
        return context.Response.WriteAsync(result);
