to overcome this I started filtering messages like that

bot.use({
    botbuilder: (session, next) => {     
        if (session.message.address.channelId === 'slack') {
            if (session.message.sourceEvent.SlackMessage) {
                if (session.message.sourceEvent.SlackMessage.type === 'message') {
                    return;
                }
            }
        }
        next();
    }
});

Glad to hear you found a way to get it working.

[nwhitmont]

thanks for the update @spawn-guy

[spawn-guy]

@JasonSowers @nwhitmont however, this is NOT a problem with my Bot.

I think this is a problem with Platform Itself! With the specific Slack channel. That exists with Newer deployments(connections). As I have another working Bot that doesn't require this hack/override.

PS: I haven't really found a page where I can report this problem other than here.

[JasonSowers]

This is the correct place to report issues. 👍

[spawn-guy]

update: I Stopped receiving double messages! Hurray!
However, I stopped receiving messages with type==message.... so I will update my snippet, as I was filtering out the wrong type of messages :/

[astjohn]

@nwhitmont, @spawn-guy - I'm experiencing the same issue. Why was this closed? Was there ever a proper fix to this? Is it expected that we use @spawn-guy's monkey patch for the slack channel forever or until Slack changes something?

[an0o0nym]

+1 to @astjohn message above. I am also having the same problem.

I'm seeing this as well, running a simple bot from the examples:

var restify = require('restify');
var builder = require('botbuilder');

// Setup Restify Server
var server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978, function () {
console.log('%s listening to %s', server.name, server.url);
});

// Create chat connector for communicating with the Bot Framework Service
var connector = new builder.ChatConnector({
appId: process.env.MICROSOFT_APP_ID,
appPassword: process.env.MICROSOFT_APP_PASSWORD
});

// Listen for messages from users
server.post('/api/messages', connector.listen());

// Receive messages from the user and respond by echoing each message back (prefixed with 'You said:')
var bot = new builder.UniversalBot(connector, function (session) {
console.log(session.message.text);
console.log(JSON.stringify(session.message, null, 2));
session.send("You said2: %s", session.message.text);
});

I'm also seeing this, though I am using C#. Will file a new issue.
