[therapy]

Code that causes the issue

channel = self._client(functions.channels.CreateChannelRequest(title='test', about=''))
channel_id = channel.to_dict()["chats"][0]["id"]
channel_hash = channel.to_dict()["chats"][0]["access_hash"]

self._channel = tl.types.InputChannel(channel_id, channel_hash)

self._client.send_message(self._channel, "test") # works fine
self._client(functions.channels.DeleteHistoryRequest(self._channel, max_id=0)) # error
