Known RPC errors

This request can cause 3 known errors:

`ChannelInvalidError`	Invalid channel object. Make sure to pass the right types, for instance making sure that the request is designed for channels or otherwise look for a different one more suited.
`ChatIdInvalidError`	Invalid object ID for a chat. Make sure to pass the right types, for instance making sure that the request is designed for chats (not channels/megagroups) or otherwise look for a different one more suited\nAn example working with a megagroup and AddChatUserRequest, it will fail because megagroups are channels. Use InviteToChannelRequest instead.
`UsernameInvalidError`	Nobody is using this username, or the username is unacceptable. If the latter, it must match r"[a-zA-Z][\w\d]{3,30}[a-zA-Z\d]".

You can import these from telethon.errors.

from telethon.sync import TelegramClient

    result = client(functions.channels.CheckUsernameRequest(
        channel='username',
        username='some string here'
    ))
    print(result)
