Hey there, thank you for this useful project.

I'm using
django ==5.0.3
django-s3file ==5.5.5
django-storages ==1.14.2

I'm using django-pictures with django-s3file to serve and store my images.
I have a model field setup like so

 image = PictureField( _("image"), upload_to=FilePattern( filename_pattern=("fancy-pattern), ), aspect_ratios=["1/1"], storage=some_s3_storage, blank=True, file_types=["WEBP", "JPEG"], width_field="image_width", height_field="image_height", )

Now if I try to save an instance of the model in the admin, I'm getting the following error message:

TypeError: object null is not iterable (cannot read property Symbol(Symbol.iterator)) at Function.from(<anonymous>) at uploadFiles(/static/s3file/js/s3file.min.7bb6c3f3de1e.js:1:164) at ? (/static/s3file/js/s3file.min.7bb6c3f3de1e.js:1:2879) at Array.forEach(<anonymous>) at uploadS3Inputs(/static/s3file/js/s3file.min.7bb6c3f3de1e.js:1:2835) at HTMLFormElement.<anonymous>(/static/s3file/js/s3file.min.7bb6c3f3de1e.js:1:3350)

If I remove blank=True from the model definition, the upload works without a problem.
Do you have an idea what is wrong here?
