Error: Bad Request: text is empty about hubot-telegram HOT 9 CLOSED

Receiving a messages via getUpdates or a webhook?

from hubot-telegram.

getUpdates

Edit: The messages are received correctly INFO Receiving message_id: 2312. Something happens when they get processed.

I am not experiencing this problem, do you perhaps have any custom heroku scripts running? The text is empty error usually happens when using sendMessage with an empty "text" parameter. The getUpdates call does not validate any text parameters.

I'm not running on heroku. I'll try disabling some scripts and see what happens.

sorry I meant hubot, not heroku XD

Seems like it happens when the bot is trying to answer a command. I have as many errors as I have commands in the getUpdates queue waiting to be processed.

It fixed itself, somehow.

You can add some debug on line 79 of telegram.coffee:

    send: (envelope, strings...) ->
        self = @
        console.log(strings.join())
        @api.invoke 'sendMessage', { chat_id: envelope.room, text: strings.join() }, (err, message) =>

If that is populated but you receive the error, it means its somehow being lost in the adapter. If the output is empty, it is possibly a bad hubot script not specifying the message string correctly...possibly some script using .hear and trying to respond to every message. I haven't been able to replicate it on my instance.

It isn't happening anymore. I just removed hubot-telegram's directory and reinstalled via npm. I will investigate further if it ever appears again. For now, I'll just close this.
