azure-functions - 如何调试从 NuGet 包导入的错误

Question

我在部署设置到我的 github 存储库 ( https://github.com/jthake/MicrosoftGraph-AzureFunctions/blob/master/MicrosoftGraphWebHook/ ) 的 Azure 函数时收到此错误。不幸的是，它不是很具体......调试它的正确方法是什么？

Microsoft.Azure.WebJobs.Host: Error indexing method 'Functions.MicrosoftGraphWebHook'. mscorlib: Multiple custom attributes of the same type found.

我在另一个线程中注意到了这个评论：

"As expcted, the Azure Functions runtime will automatically add the references to the package assemblies, so you DO NOT need to explicitly add assembly references using #r "AssemblyName", you can just add the required using statements to your function and use the types defined in the NuGet package you've referenced."

我尝试删除可能已经引用但随后在找不到程序集引用时抛出错误的 #r ref 东西。

我认为问题在于您的function.json文件缺少 http 输出绑定。尝试添加一个如下所示。至于为什么该错误会导致您收到如此神秘的错误，这是我们需要修复的错误处理错误:)

{
  "bindings": [
    {
      "webHookType": "genericJson",
      "type": "httpTrigger",
      "direction": "in",
      "name": "req"
    },
    {
      "type": "http",
      "direction": "out",
      "name": "res"
    }
  ],
  "disabled": false
}
