azure – ASP.NET 5(RC1)Bad Gateway：指定的CGI应用程序遇到错

当使用大约1.5mb或更大的文件(表单数据)调用API端点时,我会在响应主体中获得502 Bad Gateway并带有以下消息：

The specified CGI application encountered an error and the server
terminated the process.

奇怪的是,当上传较小的文件时,通话工作正常.它似乎产生了大约1.5mb标记的502,但它并不完全一致.

我正在使用ASP.NET 5 RC1.

在Startup.cs中,我有app.UseIISPlatformHandler();作为Configure()方法中的第一个中间件添加.

project.config：

编辑：

正如Jessevl所建议的那样,抛出以下异常：
