Can't deploy to Heroku

[a040900]

Hi,
when I want to use the deploy button, it's not working.

after I check what happen on internet, I saw this:
https://stackoverflow.com/questions/71892543/heroku-and-github-items-could-not-be-retrieved-internal-server-error

Looks like Heroku disconnect with github for secure reason until can fix the secure problem.

but wehn I try to deploy with heroku-CLI (also modify the .env.sample and rename to .env) and use python3 bot.py to start the bot, it always show my this on log:

Traceback (most recent call last):
File "/app/bot.py", line 24, in
APP_ID = config("APP_ID", default=None, cast=int)
File "/app/.heroku/python/lib/python3.10/site-packages/decouple.py", line 243, in call
return self.config(*args, **kwargs)
File "/app/.heroku/python/lib/python3.10/site-packages/decouple.py", line 105, in call
return self.get(*args, **kwargs)
File "/app/.heroku/python/lib/python3.10/site-packages/decouple.py", line 99, in get
return cast(value)
TypeError: int() argument must be a string, a bytes-like object or a real number, not 'NoneType'

I don't know how to fix it. Please help me.

my .env.sample file content is:
APP_ID=16917856
API_HASH=86711f61999884res2ae76cff0cdb84c2
