This is how I'm using the storage (works when I use an ASCII string):

from io import BytesIO
...
self.barcode.save(
    "Maja Majić",
    BytesIO(response.content),
    save=True
)

if you are making alot of api calls I recommend you to use the b2_storage.authorise,
it stores the seconds in your database and reuses the authorisation_token for other calls.
for this you need to include 'b2_storage.authorise', in your INSTALLED_APPS

There's no such thing as b2_storage.authorise in the code, so adding it to INSTALLED_APPS causes an Exception. Was it planned but not implemented? Was it implemented differently but not updated in the docs?

Getting this error upon installing the package and trying to upload a file.
