TypeError raised when casting InputPeerSelf to any kind of int in utils.get_peer_id

[schemacs]

I am using the latest asyncio branch 06af73e ：

  File "/home/ubuntu/.local/lib/python3.6/site-packages/telethon/telegram_client.py", line 2385, in get_entity
    for x in inputs
  File "/home/ubuntu/.local/lib/python3.6/site-packages/telethon/telegram_client.py", line 2385, in <listcomp>
    for x in inputs
  File "/home/ubuntu/.local/lib/python3.6/site-packages/telethon/utils.py", line 462, in get_peer_id
    _raise_cast_fail(peer, 'int')
  File "/home/ubuntu/.local/lib/python3.6/site-packages/telethon/utils.py", line 82, in _raise_cast_fail
    type(entity).__name__, target))
TypeError: Cannot cast InputPeerSelf to any kind of int.

This line of doc says get_input_entity will return InputPeerUser, InputPeerChat, or InputPeerChannel, but the actual code return InputPeerSelf, so this line will raise TypeError when calling utils.get_peer_id with InputPeerSelf.

Should it be changed to return await self.get_me(input_peer=True)?

I think I just need to merge master.

Thanks a lot, and should the check if peer in ('me', 'self'): in get_input_entity also changed to if peer in ('me', 'self') or isinstance(peer, InputPeerSelf):?

Came here to post exactly this issue!

In my case the problem is happening after calling the method download_profile_photo to download the profile image of the dialog Saved Messages (i.e. myself) :

  File "/home/jon/Projects/telegramstats/core/views.py", line 107, in dashboard
    x = get_profile_photo(client, dialog.entity)
  File "/home/jon/Projects/telegramstats/core/stats.py", line 74, in get_profile_photo
    return client.download_profile_photo(entity, file=os.path.join(STATICFILES_DIRS[0], f'{entity.id}.jpg'))
  File "/home/jon/.local/share/virtualenvs/telegramstats-TK1JrBmB/lib/python3.6/site-packages/telethon/telegram_client.py", line 1787, in download_profile_photo
    entity = self.get_entity(entity)
  File "/home/jon/.local/share/virtualenvs/telegramstats-TK1JrBmB/lib/python3.6/site-packages/telethon/telegram_client.py", line 2362, in get_entity
    for x in inputs

  File "/home/jon/.local/share/virtualenvs/telegramstats-TK1JrBmB/lib/python3.6/site-packages/telethon/utils.py", line 82, in _raise_cast_fail

@jonbesga You could try this:

         try:

Considering this fixed after b7ae612. If it's not please let me know and we can reopen it.

Ohh. Now I read the original issue more carefully (sorry!). Indeed that documentation line is wrong. .get_input_entity is intended when you're going to use the input version of something, not to just get the ID. If you just want the ID of yourself you should use client.get_me(input_peer=True).user_id instead. It should not be changed though because the method is fine, it returns an InputPeer (which might not have the ID).

[schemacs]

That sounds reasonable. Thanks, and you have also excluded get_peer_id from calling with InputPeerSelf in 1316e07 .
