I am trying to develop Facebook messenger chat bot. I have set my messenger and node server to talk with each other but when i try to send a message from messenger,after it reaches node server it tries to do merge action using node-wit library that in terms gives an error.
C:\Users\username\node_modules\node-wit\lib\wit.js:161
this.converse(
^
TypeError: Cannot read property 'converse' of undefined

at process._tickCallback (node.js:355:11)
here is my code:
wit.runActions(
sessionId, // the user's current session
msg, // the user's message
sessions[sessionId].context, // the user's current session state
(error, context) => {
if (error) {
console.log('Oops! Got an error from Wit:', error);
} else {
// Our bot did everything it has to do.
// Now it's waiting for further messages to proceed.
console.log('Waiting for futher messages.');
// Updating the user's current session state
sessions[sessionId].context = context;
}
}
);
Try upgrading your node to version 6. It is a version related problem. Let me know if it works fine after upgrading.

I am using the nodejs SDK for Bot Framework to develop a chatbot. I want to send a message to the user if they do not write in 5 minutes.
I do not find an example in bot-framework documentation and, in stackoverflow there are not solutions for a started bot (I do not need it to start the conversation). Where do I need to create the code? I have an index.js and a dialog file. How can I set the timer and restart it when the user send a message?
I'm using directline.
Thanks
There are two different ways you can approach this, one for directline only using events and one for all channels using setTimeout. The directline solution requires some code on your webchat client, but the latter requires you to save the conversation reference and start a new bot adapter. Both approaches could work.
Directline Only
You need to set up your webchat client to set up the timer and send an event to your bot if no activities are sent before the timer expires. You need to create a custom store to do this. Here is an example I used in the past:
const store = window.WebChat.createStore({}, function(dispatch) { return function(next) { return function(action) {
if (action.type === 'WEB_CHAT/SEND_MESSAGE') {
// Message sent by the user
clearTimeout(interval);
} else if (action.type === 'DIRECT_LINE/INCOMING_ACTIVITY' && action.payload.activity.name !== "inactive") {
// Message sent by the bot
clearInterval(interval);
interval = setTimeout(function() {
// Notify bot the user has been inactive
dispatch.dispatch({
type: 'WEB_CHAT/SEND_EVENT',
payload: {
name: 'inactive',
value: ''
}
});
}, 300000)
}
return next(action);
}}});
This will send an event to your bot with the name 'inactive'. Now you need to set up your bot to handle it. So in your this.onEvent handler you need to do something like this:
if (context.activity.name && context.activity.name === 'inactive') {
await context.sendActivity({
text: 'Are you still there? Is there anything else I can help you with?',
name: 'inactive'
});
}
All channels
As I'm typing this up, I'm realizing you should be able to emit the event from your bot itself and forego starting a new bot adapter instance. But I haven't tried that before, so I'm providing my existing solution. But you may wish to experiment with emitting an inactive event if the timeout is reached instead of the actions below.
That said, here is a solution you can use within your this.onMessage handler.
// Inactivity messages
// Reset the inactivity timer
clearTimeout(this.inactivityTimer);
this.inactivityTimer = setTimeout(async function(conversationReference) {
console.log('User is inactive');
try {
const adapter = new BotFrameworkAdapter({
appId: process.env.microsoftAppID,
appPassword: process.env.microsoftAppPassword
});
await adapter.continueConversation(conversationReference, async turnContext => {
await turnContext.sendActivity('Are you still there?');
});
} catch (error) {
//console.log('Bad Request. Please ensure your message contains the conversation reference and message text.');
console.log(error);
}
}, 300000, conversationData.conversationReference);
Note that you have to get and save the conversationReference if you go this route, so that you can call continueConversation if the timer expires. I typically do this in my this.onMessage handler as well just to make sure I always have a valid conversation reference. You can get it with the below code (I'm assuming you already have your conversation state and state accessor defined).
const conversationData = await this.dialogState.get(context, {});
conversationData.conversationReference = TurnContext.getConversationReference(context.activity);
Now as I mentioned in the first solution, I believe you should be able to send an inactivity event in your try block instead of initiating the bot adapter. If you try that and it works, please let me know so I can update this solution!
I'm trying to create a very simple Slack bot using botkit and Google App Engine, but for some reason I keep getting 401 errors any time I message the bot. The weird thing is that the Slack Event Subscription URL (the one ending in /api/messages) validates correctly, and I get a 200 response in GAE logs and validation within Slack.
But whenever I actually message the bot it always gets a 401 error with no message explaining the error at all. I've tried various combinations of the code below, and have now stripped it down to the bare minimum as found here. Aside from dependencies and a code to decrypt credentials (which I've verified is working as expected), this is my full code at the moment:
botInit();
async function botInit () {
const credentialsRaw = await getCredentials();
const credentials = JSON.parse(credentialsRaw);
const adapter = new SlackAdapter(credentials);
const controller = new Botkit({
adapter: adapter
});
controller.on('message', async(bot, message) => {
await bot.reply(message, 'I heard a message!');
});
}
I have also tried this for the messaging function:
controller.ready(() => {
controller.hears(['hello', 'hi'], ['message', 'direct_message'],
async (bot, message) => {
await bot.reply(message, 'Meow. :smile_cat:')
})
})
and this for setting up the controller:
const controller = new Botkit({
webhook_uri: '/api/messages',
adapter: adapter
});
And everything gives back the same exact 401 error, despite all of them working with the Event Subscription URL verification on Slack.
I had same issue but figured out the problem.
I had been using Client Secret as clientSigningSecret
But I should use Signing Secret !
I'm new to Slack bots so I went through their documentation and followed some tutorials on the internet but nothing seems to help. I'm trying to add a simple bot to a workspace I've just created, all I want is to make the bot post a message once it starts. Here is my code:
const SlackBot = require('slackbots');
const botToken = 'xoxp-XXXXXXXXXXXXX-XXXXXXXXXXXX-XXXXXXXXXXXXXXX-XXXXXXXXXXXXXXXXXXXXX'
const bots = async () => {
const bot = await new SlackBot({
token: botToken,
name: 'orderbot'
});
console.log('adding event listener...');
await bot.on('start', () => {
console.log('posting message...');
bot.postMessage('general', 'Feeling hungry?');
});
};
bots();
And in the OAuth & Permissions page, I've added ALL permissions to the token's scopes. Running the bot, here is my output:
adding event listener...
/home/mohammed/OrderBot/node_modules/vow/lib/vow.js:105
throw e;
^
Error: missing_scope
at /home/mohammed/OrderBot/node_modules/slackbots/index.js:46:33
So apparently, the error is coming from the .on listener which is quite confusing and I can't understand why this is happening. What exactly am I missing?
It seems like the module slackbots which I was using is not working properly (at least for me). I solved this issue by using #slack/web-api instead.
I want to open widgets.getsitecontrol.com/ javascript page that I have implemented on my website. Whenever I type 'Help' inside my bot, the widget should open. Is it possible to open it? Thanks. I am using node js version. If it is possible, please provide me an approach to solve this issue.
I'm not sure exactly how your widget functions, but when the user sends a 'help' message to the bot, you can send a back channel event to WebChat to trigger opening the widget. Take a look at the code snippets below.
Bot Code - NodeJs
When the bot receives a 'help' message from the user, the bot can send an event by sending an activity with the type set to 'event'. We can also give the outgoing activity a name attribute so we can send mutltiple types of events to WebChat. In this case, we are going to name the out going activity 'helpEvent'.
async onTurn(turnContext) {
if(turnContext.activity.type === ActivityTypes.Message) {
if (turnContext.activity.text.toLowerCase() === 'help') {
// Send Back Channel Help Event
await turnContext.sendActivity({ type: 'event', name: 'helpEvent'});
}
...
}
}
WebChat Custom Middleware
In WebChat, we are going to create a custom middleware to check incoming activities. When we encounter an activity that has a name and type that we recognize, trigger your event on the webpage. In the example below, I just alerted the use that they asked for help, but here is where you launch your widget.
const store = window.WebChat.createStore(
{},
({ dispatch }) => next => action => {
if (action.type === 'DIRECT_LINE/INCOMING_ACTIVITY') {
const { name, type } = action.payload.activity;
if (type === 'event' && name === 'helpEvent') {
// Activate Widget
alert("You asked for help.");
}
}
return next(action);
}
);
window.WebChat.renderWebChat({
directLine: window.WebChat.createDirectLine({ token }),
store,
}, document.getElementById('webchat'));
For more details on back channel events and creating a custom middleware in WebChat, checkout this sample in the WebChat Repo.
Hope this helps!
I am developing a chatbot for Facebook Messenger using Microsoft Bot Framework. The bot sends the user proactive messages (reminders). Unfortunately, for some reason the messages never show up in a chat head (the Android widget for conversations), nor pop up a chat head if it wasn't present on the screen before. It does happen for other chatbots (Jarvis, for example).
This is the code that sends the reminders:
Reminder.find({ next_reminder: { $lte: new Date() } }, (err, res) => {
if (err !== null) {
return console.error(err);
}
res.forEach(reminder => {
// Build a notification message and address it to user who created the reminder
const msg = new builder.Message().text('...');
bot.beginDialog(reminder.user_address, '*:/sendReminder', {message: msg, nudnik: nudnik});
});
});
};
};
I have also tried bot.send(msg, () => ....) and session.beginDialog('sendReminder', msg). However, there is still no indication from Messenger when the message is received. What could go wrong here?
OK, I figured it out! Apparently, the default notification setting for a Facebook message is not to show a notification. To change it, in NodeJS you should add channel-specific data to the message with the following code:
msg = msg.sourceEvent({
facebook:
{notification_type: 'REGULAR'}
});
You can discover more in official documentation by Microsoft (here and here) and also in this Github discussion.
