I get TypeError in my Django project when Debug=False

ryan

so I have this Django project, using django-cloudinary-storage . But when I turn on the Debug, I get this error saying : TypeError: expected str, bytes or os.PathLike object, not NoneType.

I don't understand what I did wrong. could you take a look at the traceback and see what went wrong? Thanks.

If you need any further info, please let me know.

Hey Ryan,

This error generally stems when trying to access a file but a None value is provided as the filename. We would need to figure out where the None value is coming from and correct the assignment. For example what the value of the open method is. Would you be able to look into any file accessing methods/functions and let us know if there are any hints there/share relevant code from those sections?
