描述你的问题

采用自定义IUnifyResultProvider方式捕捉异常，Startup类Configure方法中设置返回 200 状态码列表时，如果设置null，接口会返回200，但同时会抛出异常，（MiniProfiler不会记录起来）。

代码或代码仓库

// 添加规范化结果状态码，需要在这里注册
app.UseUnifyResultStatusCodes(options =>
{
    options.Return200StatusCodes = null; // 设置null会报错：StatusCode cannot be set because the response has already started.
    //options.Return200StatusCodes = new[] { 401, 403 }; // 配置返回 200 的状态码
});

期待结果

默认：401，403，如果设置为 null，则标识所有状态码都返回 200，不抛出异常。
