Glance image import to AWS S3 fails for files larger than 5GB

Hi Team, I have a use case where I need to replicate images from file store to S3 store. While image creation directly on S3 works fine with large files over 5G. The same fails when attempted via image-import with copy-image method. The failure is due to AWS rejecting a single object upload operation where the object size is over 5GB. What I see from logs is that direct image creation on S3 uses multipart upload when images are large. However, I fail to see the same happening when image import was used to copy an image from file to s3. Is this a known issue? Or Am I missing some configs related to image-import?
