django.core.files.uploadedfile.InMemoryUploadedFile not supported in s3transfer

[pprolancer]

I have an issue related the FilePreference when I configure my file storage as a S3Boto3Storage.
I am using storages library to have S3 storage.

the error is this:

Input 58e9197deb97430e819064f8.png of type: <class 'django.core.files.uploadedfile.InMemoryUploadedFile'> is not supported.
