Server not sending a response to Teams

Copper Contributor

I created a test messaging extension that's just supposed to go to a website link when clicked. I was able to get the app onto teams and install it to a channel, but when I try to use it or open it from the store, I get 'Unable to reach app. Please try again.' my ngrok server says "Waiting to receive a response from your server". My server code is below, I thought the callback(null, response, 200) at the bottom was supposed to send the response back to teams. Any ideas or advice is appreciated.

 

var request = require('request');
var util = require("util");
var restify = require('restify');
var builder = require('botbuilder');
var teams = require('botbuilder-teams');

var connector = new teams.TeamsChatConnector({
    appId: "myAppId",
    appPassword: "myAppPassword"
});

var server = restify.createServer();

server.listen(3978, function () {
    console.log('%s listening to app2 %s', server.name, util.inspect(server.address()));
});
var inMemoryStorage = new builder.MemoryBotStorage();
var bot = new builder.UniversalBot(connector).set('storage', inMemoryStorage);

var stripBotAtMentions = new teams.StripBotAtMentions();
bot.use(stripBotAtMentions);

bot.dialog('/', [
    function (session) {
        builder.Prompts.text(session, 'Hi! What is your name?');
    },
    function (session, results) {
        session.endDialog(`Hello ${results.response}!`);
    }
]);

// this will reset and allow to receive from any tenants
connector.resetAllowedTenants();

// var bot = new builder.UniversalBot(connector);

server.post('/api/composeExtension', connector.listen());
server.post('/api/messages', connector.listen());
// server.post('/greetings', connector.listen());
server.post('/', connector.listen());

var composeExtensionHandler = function (event, query, callback) {
    // parameters should be identical to manifest
    console.log("Query Running");
    
    var attachments = [];
    try {
        console.log('hit')
        var card = new builder.HeroCard()
        .buttons([{
            type: "openUrl",
            title: "Open Kloud",
            value: 'kloud.com'
        }]);
        
        attachments.push(card.toAttachment());
        
        
    } catch (err) {
        console.log(err);
    }
    
    
    var response = teams.ComposeExtensionResponse
        .result('list')
        .attachments(attachments)
        .toResponse();

    // Send the response to teams
    callback(null, response, 200);

        //}

};

connector.onQuery('Open', composeExtensionHandler);

var composeInvoke = function (event) {
    console.log(event);
};


connector.onInvoke(composeInvoke);

@marcusyoung Could you please try the sample here for Message Extension and see if you are facing any issue?

@Gousia_Begum I'm getting a response, but now I'm getting TypeError: BotFrameworkAdapter is not a constructor. I botbuilder installed already and I've tried different versions of it.

Fixed the problem by manually installing the latest version of botbuilder. Seems like the normal npm i was installing a previous version.
