servicestack - 请求正文太大

Question

当我尝试将 80mb 文件从 postman 上传到我在 IISExpress 上的 Visual Studio 2019 中运行的本地端点时，我收到以下错误:

The request filtering module is configured to deny a request that exceeds the request content length.

所以我将它添加到了项目的 applicationhost.config 中:

<system.web>
      <httpRuntime maxRequestLength="1050000" /> 
    </system.web>
    <system.webServer>
        <security>
            <requestFiltering>
                <requestLimits maxAllowedContentLength="1073741824"/>
            </requestFiltering>
        </security>

当我发出 API 请求时，这会阻止错误的发生，但现在我只是得到一个 ServiceStack 生成的“快照”页面，告诉我请求花费了多长时间和日期，但我的实际端点从未被命中。
在我的日志中，我可以看到 ServiceStack 抛出此异常:

所以 body 长度仍然需要在某处设置，但我看的每个地方都指向我已经使用过的配置。
是否需要额外设置或者这是一个 ServiceStack 问题？

我在启动时缺少这个选项:

services.Configure<IISServerOptions>(options =>
{
    options.MaxRequestBodySize = int.MaxValue;
});

services.Configure<KestrelServerOptions>(options =>
{
    options.Limits.MaxRequestBodySize = int.MaxValue; // if don't set default value is: 30 MB
});
