Python with open doesn't create new file after deployed at Heroku

I'm working on a python project in which I need to create a new JSON file.It's working locally but when I deploy my app to Heroku the file creation doesn't work.

Here's what I have tried:

From settings.py

APP_ROOT = os.path.dirname(os.path.abspath(__file__))   # refers to application_top
APP_FINALIZED = os.path.join(APP_ROOT, 'finalized')

From app.py

HOME = os.path.join(APP_FINALIZED)
print(HOME)
with open(HOME + '/description_' + str(fid) + '.json', 'w', encoding="utf-8")\
        as f:
    f.write(json.dumps(data, indent=4, ensure_ascii=False))

Updated: can we write this file directly to the S3 bucket, anyway?

it's working fine locally, but when I deploy it on Heroku the file doesn't create, even it doesn't show any error.

I'll add this as answer as well in case someone elese needs help. Heroku's file system is (as far as I can remember) read-only. Please check this answer.
