Google Dialogflow webhook 中未调用云函数

Question

我正在创建一个 Google 助手操作，我在其中使用了 firebase 云函数并将代码部署到 firebase 云函数。

我已经复制了 webhook url 并将其粘贴到 Dialogflow 控制台中，并为默认欢迎意图启用了 Webhook 调用。

当我运行代码时，我收到如下错误

这里是云函数代码

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

现在代码正在运行，现在已完成以下步骤以使其运行。如果有人遇到此类问题，请检查以下步骤。

根本原因#1

在 Dialogflow 控制台中，我删除了导致上述错误的默认欢迎意图中的所有默认响应。所以我添加了一个默认响应并测试了工作正常的操作。但是没有显示云函数的响应。

根本原因#2

尝试使用 Dialogflow 中的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，但它没有启用说明 Google 需要配置云，请刷新页面。查看 GCP 控制台并比较我创建的其他操作，每个操作都有存储，但这个操作没有，所以我在启用存储内联编辑器后在 Firebase 中创建了存储（在 Dialogflow 中提出查询以确认是否是因为内联编辑器没有打开的存储）。

解决方案 1

打开内联编辑器后，粘贴上面的代码和 package.json 文件并部署代码并测试它按预期工作

解决方案 2

尝试从我的机器部署相同的代码并启用 Webhook 而不是内联编辑器并测试操作按预期工作

解决方案 3

将导出 dialogflowFirebaseFulfillment 名称更改为 fulfillment 并部署代码并测试它不起作用所以比较两个函数并找到fulfillment 函数没有像下图那样的权限

如果您注意到上图中有一个名为 allUsers 的角色，而在 fulfillment 函数中它没有 allUsers角色

如果您查看功能仪表板 (dialogflowFirebasefulfillment)，您会注意到其中的区别

履行（仪表板）

要为其启用权限，请单击信息面板并单击 添加成员 并添加 allUsers，如下所示

完成后，通过单击 Cloud Functions 和 Cloud Functions Invoker 为 allUsers 添加角色，然后单击保存。

现在您可以看到更新后的仪表板，如下所示

现在，如果您测试操作，它将调用云函数。
