Actions Sdk get this error TypeError: Cannot read property 'output' of undefined

Question

我正在尝试连接 IBM Watson 和 Google Assistant，但我一直收到此错误 "TypeError: Cannot read property 'output' of undefined" 和此 "Function execution took 3323 ms, finished with status: 'crash'"

这是我的代码：

const {actionssdk} = require('actions-on-google');
const functions = require('firebase-functions');

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

app.intent('actions.intent.MAIN', (conv) => {
    conv.ask('Olá, como posso lhe ajudar?');
});


app.intent('actions.intent.TEXT', (conv, input) => {
    var AssistantV1 = require('watson-developer-cloud/assistant/v1');
    var assistant = new AssistantV1({
        username: '###################################',
        password: '###################################',
        url: '###################################',
        version: '2018-07-10'
    });
    conv.ask("eeeeeeeeeeeeeeeee");
    return new Promise( (resolve, reject) => {
        assistant.message(
        {
          workspace_id: '###################################',
            input: { text: input },
            headers: {'Content-Type':'application/json'}
        },
        function(err, response) {
            conv.ask(response.output.text[0]);
            resolve();
        }
        );
     })
});
exports.dialogflowFirebaseFulfillment = functions.https.onRequest(app);

Rebeca，只是为了添加信息，您正在尝试添加一些出站访问权限，但您需要配置您的帐户才能执行此操作。

"Billing account not configured. External network is not accessible and quotas are severely limited. Configure billing account to remove these restrictions"

如果您想打电话给一些 API（IBM Watson，已验证），您需要启用计费。

对于其他配额，take a look here to see prices - 如您所见，使用免费套餐的调用次数有限制。

Answer 2

您的response对象为空。在使用之前检查它是否不等于 null:

let speech;
if (response !== null) {
    speech = response.output.text[0];
}
else{
    speech = "I'm sorry, there was an error and I'm unable to answer";
}
conv.ask(speech);
