Dialogflow webhook中未调用Google Cloud函数

Question

我正在创建Google Assistant操作，其中我使用了Firebase云功能并将代码部署到Firebase云功能。

我复制了Webhook URL并将其粘贴到Dialogflow控制台中，并为Webhook调用启用了默认的欢迎意图。

当我运行代码时，出现如下错误

这里是云功能代码

const { dialogflow, Suggestions } = require("actions-on-google");

const functions = require("firebase-functions");

const app = dialogflow({ debug: true });

app.intent("Default Welcome Intent", conv => {
  if (conv.user.last.seen) {
    conv.ask(`Welcome back to Standup Sheet`);
  } else {
    const ssml = `<speak>Welcome to Standup Sheet. I will assist you to know about your teams daily task as well the over all time taken for each project.</speak>`;
    conv.ask(ssml);
  }
  conv.ask(
    new Suggestions(["Todays entries", "Yesterday entries", "Team", "Projects"])
  );
});

exports.dialogflowFirebaseFulfillment = functions.https.onRequest(app);

Package.json文件

Answer 1

现在，代码可以按照以下步骤进行操作以使其正常工作。如果有人遇到这种问题，请检查以下步骤。

根本原因＃1

在Dialogflow控制台中，我已删除导致上述错误的默认欢迎意图中的所有默认响应。因此，我添加了默认响应并测试了效果良好的操作。但是未显示来自云功能的响应。

根本原因＃2

试图在Dialogflow中使用内联编辑器，并检查是否正在调用该函数。尝试启用内联编辑器，但未启用声明需要配置Google Cloud，请刷新页面。查看了GCP控制台，并比较了我创建的每个操作所具有的其他操作都具有存储，但是此操作没有，因此我在启用了存储内联编辑器后在Firebase中创建了存储（在Dialogflow中引发查询以确认是否是由于存储不会打开内联编辑器）。

解决方案1

一旦打开内联编辑器，将上面的代码和package.json文件粘贴并部署代码并对其进行了测试，并按预期工作了

解决方案2

试图从我的计算机上部署相同的代码并启用了Webhook而不是嵌入式编辑器，并测试了该操作是否按预期工作

解决方案3

将导出dialogflowFirebaseFulfillment名称更改为fulfillment，并部署了代码并对其进行了测试，因此对这两个函数进行了比较，发现fulfillment函数没有以下权限：下图
