Error when upload files to Azure Blob storage through Django App - django

Question

I need to build a file manager to upload images from a Django app to Azure blob storage. However, when I try to upload a file to Azure's blob storage, I get the following error:
Traceback (most recent call last):

Some of the documentation I read advises using a Security Prncipal in Azure, which implies setting up Azure AD, but every time I try to go to Azure AD in my account, I get a message saying I'm not allowed (I'm the owner of the account). I honestly have no idea where to go from here or how to begin to fix this. Can someone help?
Any help will be greatly appreciated
