Error: expected str, bytes or os.PathLike object, not NoneType about django-sri HOT 5 CLOSED

Interesting, i'm not seeing anything in that which looks specifically wrong.

Is there any more of a stack trace which tells you which line in the library is the issue? This will likely be in the django logs rather than being shown in the page.

from django-sri.

Sorry, here is the stack trace.

hmm interesting. Looks like that's coming from https://github.com/RealOrangeOne/django-sri/blob/master/sri/utils.py#L27.

Do you have STATIC_ROOT defined in your settings?

from django-sri.

No actually, my project currently using STATICFILES_DIRS.

from django-sri.

ah, ok, I see the issue. It looks like it's incorrect to be reading files direct from STATIC_ROOT as I am. It should instead look at those dirs.

There's probably a helper in Django for getting the filesystem path of a static file somewhere, i'll give it a look over the weekend

from django-sri.
