Upload of large images fail: "uploaded file is empty"

[tuhe]

Hi, I don't know if this is a bug or intentional behavior, but I am having problems uploading large images in ckeditor 5.

I am using the django-ckeditor5 plugin (https://pypi.org/project/django-ckeditor-5/) and I noticed that if I copy-paste a large image the plugin will fail (image has size zero on the server) and I have been unable to find a workaround (preferably just remove the limit or alternative resize the image). I have noticed that the problem also occur with the examples on the website. For instance, if I copy paste this wallpaper:

https://www.freepik.com/free-photo/galaxy-nature-aesthetic-background-starry-sky-mountain-remixed-media_17226410.htm#query=wallpaper&position=1&from_view=keyword&track=ais_hybrid&uuid=2e1cb989-c083-4564-ba22-1cc1fe69ef9e

I get this error:

(copy-pasting smaller regions work, obviously).

I am unable to find an appropriate setting, workaround, or warning that the image cannot be too big. The link in the error points to:

https://ckeditor.com/docs/ckeditor5/latest/support/error-codes.html#error-fileuploader-uploading-data-failed

which is not very helpful. I am observing the behavior on Chrome/Firefox on Kubuntu 24.04 as well as Safari/MacOS.
