Amazon Lex and BotFramework integration TypeError: Cannot perform 'get' on a proxy that has been revoked at Response

Question

我正在做一个概念验证，试图将 BotFramework 与 Amazon lex 集成，并最终将机器人集成到 Microsoft 团队频道。 AWS-SDK 用于调用 Amazon Lex 机器人。

async callLex(context) {
    let msg 
    var lexruntime = new AWS.LexRuntime();
    const params = {
         botAlias: 'tutorialbot',
         botName: 'TutorialBot',
         inputText: context.activity.text.trim(), /* required */
         userId: context.activity.from.id,
         //inputStream: context.activity.text.trim()
    }

    await lexruntime.postText(params, function(err,data) {
        console.log("Inside the postText Method")
        if (err) console.log(err, err.stack); // an error occurred
        else {
            console.log(data)
            msg = data.message
            console.log("This is the message from Amazon Lex" + msg)
            context.sendActivity(MessageFactory.text(msg));
            //turnContext.sendActivity(msg);
        }

        console.log("Completed the postText Method")
    })

    return msg; 
}

接收到来自 Lex 的响应，当我尝试 return 返回相同的响应时 context.sendActivity(MessageFactory.text(msg)) 在 BotFramework 的回调函数中抛出错误

Blockquote TypeError: Cannot perform 'get' on a proxy that has been revoked at Response. (E:\playground\BotBuilder-Samples\samples\javascript_nodejs.echo-bot\lexbot.js:93:25) at Request. (E:\playground\BotBuilder-Samples\samples\javascript_nodejs.echo-bot\node_modules\aws-sdk\lib\request.js:369:18) at Request.callListeners (E:\playground\BotBuilder-Samples\samples\javascript_nodejs.echo-bot\node_modules\aws-sdk\lib\sequential_executor.js:106:20) at Request.emit (E:\playground\BotBuilder-Samples\samples\javascript_nodejs.echo-bot\node_modules\aws-sdk\lib\sequential_executor.js:78:10)

消息发送给 Lex 后，机器人使用的代理似乎不再可用。你能给出一些关于如何解决这个问题的建议吗？

这是调用异步函数callLex的调用代码

class TeamsConversationBot extends TeamsActivityHandler {
    constructor() {
        super();
        this.onMessage(async (context, next) => {
            TurnContext.removeRecipientMention(context.activity);
            var replyText = `Echo: ${ context.activity.text }`;
                    
            await this.callLex(context)
          
            console.log("After calling the callLex Method")
         
            await next();
        });

        this.onMembersAddedActivity(async (context, next) => {
            context.activity.membersAdded.forEach(async (teamMember) => {
                if (teamMember.id !== context.activity.recipient.id) {
                    await context.sendActivity(`Hi, I'm a TutorialBot. Welcome to the team ${ teamMember.givenName } ${ teamMember.surname }`);
                }
            });
            await next();
        });
    }

此错误消息始终表示您没有等待应等待的内容。您可以在构造函数中看到以下行：

await context.sendActivity(`Hi, I'm a TutorialBot. Welcome to the team ${ teamMember.givenName } ${ teamMember.surname }`);

这应该向您暗示需要等待 sendActivity，但您并未在 postText 回调中等待它：

await lexruntime.postText(params, function(err,data) {
    console.log("Inside the postText Method")
    if (err) console.log(err, err.stack); // an error occurred
    else {
        console.log(data)
        msg = data.message
        console.log("This is the message from Amazon Lex" + msg)
        context.sendActivity(MessageFactory.text(msg));
        //turnContext.sendActivity(msg);
    }

    console.log("Completed the postText Method")
})

您正在等待对 postText 本身的调用，但这不会执行任何操作，因为 postText returns 是请求而不是承诺。你可能已经注意到你不能在回调中等待任何东西，因为它不是异步函数。 Lex 包似乎是 callback-based 而不是 promise-based，这意味着它很难与 Bot Framework 一起使用，因为 Bot Builder SDK 是 promise-based.

您可能想致电 PostText API directly using a promise-based HTTP library like Axios: use await inside callback (Microsoft Bot Framework v4 nodejs)

或者您可以尝试 creating your own promise and then awaiting that:
