本地主机上的Azure功能代理404

我有一个Azure函数应用程序,在URL上有一个函数 http://localhost:7072/api/create-room 以及其他功能。这个特殊的函数是 HTTPTrigger 允许匿名访问并接受 GET 动词:

[HttpTrigger(AuthorizationLevel.Anonymous, "get")]

proxies.json 文件,仅用作函数代理。我的代理功能正在端口上运行 7071

{
    "$schema": "http://json.schemastore.org/proxies",
    "proxies": {
      "chatNegotiate": {
        "matchCondition": {
          "route": "/api/chat/negotiate",
          "methods": [
            "POST"
          ]
        },
        "backendUri": "%chat_api%/api/BeginNegotiate"
      },
      "chatMessages": {
        "matchCondition": {
          "route": "/api/chat/messages",
          "methods": [
            "POST"
          ]
        },
        "backendUri": "%chat_api%/api/PostMessage"
      },
      "createRoom": {
        "matchCondition": {
          "route": "/api/create-room",
          "methods": [
            "GET"
          ]
        },
        "backendUri": "%session_api%/api/CreateRoom"
      }
    }
}

当这两个功能应用程序都部署到Azure时,一切都像做梦一样工作。我可以提出请求,它们被转发,请求被回复。一切都很光荣。

但是,当我在本地运行这些函数时,请求永远不会从代理转发,代理返回404。我可以点击在本地运行的其他函数应用程序上的函数 7072

代理本身返回:
