Question

我正在使用dialogflow-fulfillment的0.5.0版本。

这是测试功能

function test(agent){
   let conv = agent.conv();
   conv.ask("HEY");
   agent.add(conv);  // line 54
}

在Google模拟器上测试操作时遇到的错误

TypeError: Cannot read property 'forEach' of undefined
    at V2Agent.addActionsOnGoogle_ (/user_code/node_modules/dialogflow-fulfillment/src/v2-agent.js:334:28)

    at _combinedTickCallback (internal/process/next_tick.js:73:7

这是完整的代码

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
  const agent = new WebhookClient({ request, response });

  console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
  console.log('Dialogflow Request body: ' + JSON.stringify(request.body));

function test(agent){
    let conv = agent.conv();
    conv.ask("HEY");
    return agent.add(conv);
}

let intentMap = new Map();
intentMap.set('test', test);

 agent.handleRequest(intentMap);

});

记录说Dialogflow请求正文的行

Answer 1

我遇到了同样的问题，将packages.json中的依赖项更新为以下解决了该问题：

"actions-on-google": "^2.5.0",
"dialogflow-fulfillment": "^0.6.1"

Answer 2

将conv作为默认会话变量，请尝试使用其他变量

agent.add（conv）在dialogflow-fulfillment-library中不起作用？
