systemd service keep giving me error when start or get status

I have a python application and I need it to be run as a service, I tried many methods and I was advised to make it as systemd service

I searched and tried some code

here is my unit code

[Unit]
Description=Airnotifier Service
After=network.target

[Service]
Type=idle
Restart=on-failure
User=root
ExecStart=python3 /home/airnotifier/airnotifier/app.py

[Install]
WantedBy=multi-user.target

and then I run the following commands

sudo systemctl daemon-reload
sudo systemctl enable airnotifier.service
sudo systemctl start airnotifier.service
sudo systemctl status airnotifier.service

the service does not run and I am getting this errors

airnotifier@airnotifier:~$ sudo systemctl status airnotifier.service
● airnotifier.service - Airnotifier Service
