Not really sure what to do from here. Is this related to my requirements.txt file? This is my first time deploying an app so I followed the guide and not sure what/where I went wrong.
Thanks for the help!

Hello @bigaquamarinesnorkler,
The error you are facing is likely due to a compatibility issue between the package and the Python version you are using.
- Check your Python version: Make sure you are using a compatible Python version for your project. You can specify a Python version by including a
runtime.txtfile in the root directory of your project with the desired version, for example:
- python-3.9.9
DigitalOcean’s App Platform will use this file to set the appropriate Python version during deployment.
- Check your
requirements.txtfile: Ensure that all the packages and their versions are compatible with your Python version. You can also try updating thebackports.zoneinfopackage to the latest version by specifying it in yourrequirements.txtfile:
- backports.zoneinfo==latest_version
- If updating the package does not work, you can try using an alternative package with similar functionality, such as
pytz. Replacebackports.zoneinfowithpytzin yourrequirements.txtfile. Please note, if it comes to this, After making these changes, you will need to modify your Django project to use the new package.
