Are you running the app with any sort of reduced permission scope? Maybe from an EC2 instance (so you're using its instance profile)? Or maybe you're using a transformation to change the ACLs on the bucket?

You could also check the access logs of whichever role is in use, to see why the uploads are not being permitted. That might help you figure out which permission you need to add.
