KeyError exception in __init__.py line 792

Telepot throws an exception while retrieveing messages from telegram servers. Here's the traceback:

(traceback from OSX)

Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/telepot/__init__.py", line 792, in get_from_telegram_server offset = max([relay_to_collector(update) for update in result]) + 1 File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/telepot/__init__.py", line 792, in <listcomp> offset = max([relay_to_collector(update) for update in result]) + 1 File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/telepot/__init__.py", line 779, in relay_to_collector 'chosen_inline_result']) File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/telepot/__init__.py", line 61, in _find_first_key raise KeyError(keys) KeyError: ['message', 'edited_message', 'callback_query', 'inline_query', 'chosen_inline_result']

Here's the code:

bot_token = "xxxxxxxxxxxxx"

#mock handle function
def handle(msg):
    chat_id = msg['chat']['id']
    type = msg['chat']['type']
    message_id = msg['message_id']
 
    bot.sendMessage(chat_id, "Test")

bot = telepot.Bot(bot_token)
bot.message_loop(handle) #Exception thrown here

while 1:
	time.sleep(10)

My bot no longer receives messages

[Shayan123456]

Yeah When I send message to bot from Channel I receive this error Too:
line 61, in _find_first_key raise KeyError(keys) KeyError: ['message', 'edited_message', 'callback_query', 'inline_query', 'chosen_inline_result']

@Shayan123456 @nickoala The issue is related to Telegram Channels.
They're not supported by telepot so the bot crashes, but the messages remains in the telegram's queue (that's why my bot crashes on startup).
We need support for channels in telepot.

Here's a sample message that will make it crash (from https://api.telegram.org/botXXXXXXXXXXX/getUpdates):

{"update_id":441783091,` "channel_post":{"message_id":1291,"chat":{"id":<channel_id>,"title":"<channel_title>","username":"<username>","type":"channel"},"date":1479733054,"text":"<some long unicode message>"}}

My bot was added as a channel admin.

So the exception is thrown as the message type is "channel_post" (or also "edit_channel_post") which is not included in https://github.com/nickoala/telepot/blob/master/telepot/__init__.py at line 776

Here's quick and dirty fix: replace relay_to_collector function in init.py at line 774 with this one:

def relay_to_collector(update):
            key = _find_first_key(update, ['message',
                                           'channel_post',
                                           'edited_channel_post',
                                           'edited_message',
                                           'callback_query',
                                           'inline_query',
                                           'chosen_inline_result'])
            collect_queue.put(update[key])
            return update['update_id']

This will at least prevent the bot from crashing on startup.
Thanks to https://github.com/ruste96 for this fix

[nickoala]

This seems to be related to the changes in Bot API 2.3. Expect an update on or before Nov 30.

[R0bertoG]

Can I suggest a better error message?
Something like:

def _find_first_key(d, keys):
    for k in keys:
        if k in d:
            return k
    raise KeyError("Server returns a key that it's not in " + str(keys))

Maybe even return what is the name of the not expected key. I was coding when the error started to happen and I spent sometime until I undernstood what the problems was.

[efazati]

I have same error
how can fix this?

Traceback (most recent call last):

[carloalbertobarbano]

Okay so here's the solution to fix telepot with the new API (2.3):

Replace function relay_to_collector in file init.py at line 774 with:

def relay_to_collector(update):
            key = _find_first_key(update, ['message',
                                           'channel_post',
                                           'edited_channel_post',
                                           'edited_message',
                                           'callback_query',
                                           'inline_query',
                                           'chosen_inline_result'])
            collect_queue.put(update[key])
            return update['update_id']

Now in your bot's code to find out the chat type you can do:

def handle(msg):
    type = msg['chat']['type']

    if type == "private":
          #message from msg['chat']['first_name']
    else:
          #message from msg['chat']['title']

I'd wait until the next release of telepot to mark this issue as closed.

[efazati]

@carloalbertobarbano I use something like this

class AppManager(telepot.helper.ChatHandler):
    def __init__(self, *args, **kwargs):
        super(AppManager, self).__init__(*args, **kwargs)


    def on_chat_message(self, msg):
        content_type, chat_type, chat_id = telepot.glance(msg)

        user, is_first_time = get_or_create_user(self.sender, msg, True)

[carloalbertobarbano]

@efazati you have to edit the telepot library yourself for now. Just replace the function in this file https://github.com/nickoala/telepot/blob/master/telepot/__init__.py as described above.

You can find the correct path for that file on your machine in the traceback of the exception

[efazati]

@carloalbertobarbano I did change that code, but what about handle in my code? i use with this method and i dont have method like your handle

i mean this

def handle(msg):
    type = msg['chat']['type']

    if type == "private":
          #message from msg['chat']['first_name']
    else:
          #message from msg['chat']['title'

[carloalbertobarbano]

@efazati That was just a sample. You can use telepot in the way you are used to without further changes.
For any doubts about implementation refer to the Telepot Api Reference http://telepot.readthedocs.io/en/latest/reference.html or contact the author @nickoala

Let's keep this thread for this library bug only and free from other implementation-specific issues.

[gonardfreeman]

For all who dont want to wait update u can fix this problem by theyself, just add at 780 string at init.py (in relay_to_collector(update) this function) to list one value 'channel_post'

[gonardfreeman]

Oh, im sort of slowpoke)) sorry)

[96Octavian]

Following this issue, how could I know which channel my bot has been added to? Is there a way?

[nickoala]

@96Octavian, when a bot is added to a group, it receives a new_chat_member. But when added to a channel ...... I am not sure what notification you will get, if you get any notification at all. 🤔

On the other hand, I have updated telepot (10.2) to encompass Bot API 2.3. Just do:

pip install telepot --upgrade

This issue should be no more. Thanks everyone for using telepot 😊

Same error in the latest bot API update when working with polls.

got a monkey patch like this for the Bot API 4.2 poll update?
