Problems with sending two times the same file/photo

[pfasciani]

I'm creating a bot for me and my classmates and i'm struggling with this error

Traceback (most recent call last): File "build/bdist.macosx-10.13-intel/egg/telepot/__init__.py", line 1158, in collector callback(item) File "/Users/piergiuliofasciani/Documents/bot.py", line 30, in on_chat_message [KeyboardButton(text="Torna al menu principale")] File "build/bdist.macosx-10.13-intel/egg/telepot/__init__.py", line 539, in sendPhoto return self._api_request_with_file('sendPhoto', _rectify(p), 'photo', photo) File "build/bdist.macosx-10.13-intel/egg/telepot/__init__.py", line 499, in _api_request_with_file return self._api_request(method, _rectify(params), files, **kwargs) File "build/bdist.macosx-10.13-intel/egg/telepot/__init__.py", line 491, in _api_request return api.request((self._token, method, params, files), **kwargs) File "build/bdist.macosx-10.13-intel/egg/telepot/api.py", line 155, in request return _parse(r) File "build/bdist.macosx-10.13-intel/egg/telepot/api.py", line 150, in _parse raise exception.TelegramError(description, error_code, data) TelegramError: (u'Bad Request: file must be non-empty', 400, {u'error_code': 400, u'ok': False, u'description': u'Bad Request: file must be non-empty'})

This occurs only when I ask two times for the same Photo or File without restarting the bot.

Can I fix this?

Here's my code

`import telepot

command = msg['text']

Hello @pfasciani

The problem is not from the telepot module. Its something with the io.BufferedReader built-in module, i don't know what happens but here is the workaround:

Open the file every time you need to send the photo instead once globally.
Sample:

elif command == emoji.emojize(":watch: Orario :watch:", use_aliases=True):
with open("/Users/piergiuliofasciani/Desktop/orario.jpg", 'rb') as photo:
bot.sendPhoto(chat_id, photo, "Ecco qui",
reply_markup=ReplyKeyboardMarkup(
keyboard=[
[KeyboardButton(text="Torna al menu principale")]
]
)),

Hope this will help you.
