Thanks for the fix. It sounds to me like this module was treating utils as an attribute of webpack_loader, but it's actually a sub-module. So, when webpack_loader.utils happened to be imported, the code worked, but when it wasn't imported, we got an AttributeError.

Does your fix still work if you put from webpack_loader.utils import get_files at the top of the module instead of within the function?

I tried importing it at the top of the file, but it resulted in this error:
