Issue when I use the multi-page bot example

[mronceray]

Hi 👋 I want to thank @jdwuarin who worked on on the support of several Facebook pages. I did some tests using two pages.

I had this error at first

/Users/maxime/BotMasterTest/app.js:19
    fbAppSecret: '***',
    ^^^^^^^^^^^
SyntaxError: Unexpected identifier
    at Object.exports.runInThisContext (vm.js:76:16)
    at Module._compile (module.js:542:28)
    at Object.Module._extensions..js (module.js:579:10)
    at Module.load (module.js:487:32)
    at tryModuleLoad (module.js:446:12)
    at Function.Module._load (module.js:438:3)
    at Module.runMain (module.js:604:10)
    at run (bootstrap_node.js:394:7)
    at startup (bootstrap_node.js:149:9)
    at bootstrap_node.js:509:3

The error was no longer displayed by placing "fbAppSecret" above "pages" like that

const messengerSettings = {
  credentials: {
    verifyToken: 'TOKEN',
    fbAppSecret: '***',
    pages: {
      'pageID1': { pageToken: '***' },
      'pageID2': { pageToken: '***' },
    }
  },
  webhookEndpoint: 'webhook',
};

But I still have an error that I do not understand how to debug it

I have this error in my terminal when I send a message to my facebook page (node:73321) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 3): Error: Uncaught, unspecified "error" event. ([object Object])

I'm not sure if I'm using the example correctly, do you know where the error comes from?

Thank you for your reply

Can you post all the code you are running so I see where the error could come from?

Also, the Readme was a bit off. Thanks for pointing that out. Updating it now

const Botmaster = require('botmaster');
const MessengerBot = require('botmaster-messenger');
const botmaster = new Botmaster();

const messengerSettings = {
    credentials: {
      verifyToken: 'TOKEN',
      fbAppSecret: 'fdbd2ec***',
      pages: {
        '1572***': {
          pageToken: 'EAAN***'
        },
      '10227***': {
        pageToken: 'EAAN***'
      },
      '177399***': {
        pageToken: 'EAAN***'
      }
    }
  },
  webhookEndpoint: 'webhook',
};

const messengerBot = new MessengerBot(messengerSettings);

botmaster.addBot(messengerBot);

botmaster.use({
  type: 'incoming',
  name: 'my-middleware',
  controller: (bot, update) => {
    const messageToSend = bot.createOutgoingMessageFor(userId);
    messageToSend.addText('Hello World');
    messageToSend.sender = {
      id: '1773***',
    };
    return bot.sendMessage(messageToSend);
  }
});

Right. Another issue with the Readme; Your middleware should read:

botmaster.use({
  type: 'incoming',
  name: 'my-middleware',
  controller: (bot, update) => {
    const messageToSend = bot.createOutgoingMessageFor(update.sender.id); // or another userId you know about
    messageToSend.addText('Hello World');
    messageToSend.sender = {
      id: '1773***',
    };
    return bot.sendMessage(messageToSend);
  }
});

Perfect, it works! Thank you

Just to let you know that I just deployed a new version that will let you use multi-pages like before. I.e. no need to specify the pageId (only works within middleware) - as the pageId defaults to whichever page received an update. This means, all the reply, send* functions will now work also for multi-page bots. Checkout the updated docs.
