ImportError: cannot import name 'zoneinfo' from 'backports' (unknown location)

I am trying to deploy my Django model on an Apache2 server and it is running well on 'ip':8000. But when i am trying to run without 8000 port after completing all prerequisites i am getting this error

I installed mod_wsgi correctly for Python 3.8.10

#wsgi.py

 import os, sys
 import site
 site.addsitedir('/root/novo-ai-api-main/backend/dj/lib/python3.8/site-packages')
 from django.core.wsgi import get_wsgi_application
 os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'server.settings')
 application = get_wsgi_application()

Also I have given permissions to all the working files but nothing happened

#### 
    drwx--x--x  9 root     root       4096 Jun 16 22:05 .
    drwxr-xr-x 19 root     root       4096 Jun 14 14:05 ..

What can I try next?

ModuleNotFoundError: No module named 'backports' I solved this error by first removing the package backports.zoneinfo from my project and then re-install by typing pip install backports.zoneinfo[tzdata]

Finally I have solved this issue by giving permissions to all files and directories in my Django project. Using this command

find /root/novo-ai-api-main -type d -exec chmod 755 {} \;

It solved my many errors related to modules. If you are new to Apache deployment make sure you give right permissions to all files in directories.
