I am trying to deploy a simple user bot on Google App Engine Flexible Environment running python3.7, but I get the following error. Can anyone help me with suggestions of solving this?
"File "/env/lib/python3.7/site-packages/telethon/client/auth.py", line 20, in  phone: typing.Callable[[], str] = lambda: input('Please enter your phone (or bot token): '), EOFError: EOF when reading a line"
Thank you for your time
Telethon (obviously) requires you to login and make a normal user session on your account, which natively requires you to input your number when asked and enter the code received but since Google App engine doesn't allow input as @Sashidhar mentioned, depending on your userbot implementation, you can try using the userbot.session method for authentication, it can be generated locally and placed in the Google App Engine.
