But the objects inside the bucket have full control:
Cause
Bucket and object permissions are independent of each other. An object does not inherit the permissions from its bucket.
Resolution
Bucket write permission is enough to delete objects in the bucket.
If the user has only write permission to the bucket and we can delete the object, it is working as expected.
For more information, see this AWS Configuring ACLs document.
If you want to set permissions at the object level, the workaround is to use bucket policy. To create a bucket policy, review the Data Access Guide for your ECS code version.
