Django ckeditor 5 upload images to Google Cloud Bucket

Question

I am trying to use the package django-ckeditor-5 on my webapp. I am using django-storages with storages.backends.gcloud.GoogleCloudStorage backend. I have set these settings: CKEDITOR5_FILE_STORAGE = 'storages.backends.gcloud.GoogleCloudStorage' CKEDITOR_5_UPLOADS_FOLDER = 'uploads/'

However, when I try to upload an image, I get this error:

Internal Server Error: /ckeditor5/image_upload/
Traceback (most recent call last):
  File "/opt/homebrew/Caskroom/miniforge/base/envs/stokk/lib/python3.9/site-packages/django/core/handlers/exception.py", line 47, in inner

AttributeError: 'PosixPath' object has no attribute 'startswith'

Other relevant settings:

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
MEDIA_ROOT = os.path.join(BASE_DIR, 'media') 
MEDIA_URL = '/media/'

django-ckeditor4 worked fine, so is it a question of supporting GCB storage or am I missing something in my settings?
