[BUG] Missing required header X-Amz-Content-Sha256 on copy between bucket

[noiretr-cg]

Hello,

I am trying to copy a file between two buckets using a public S3 endpoint (different AWS region) but but it seems that the header is missing. (This header seem required for authentification with AWS https://docs.aws.amazon.com/AmazonS3/latest/API/bucket-policy-s3-sigv4-conditions.html)

s5cmd version
v2.0.0-35bb2fa

s5cmd -r 1 --endpoint-url s3.eu-west-3.amazonaws.com --log debug cp --source-region eu-west-3 --destination-region eu-west-1 s3://bucket-source/xx[ABC].zip s3://bucket-dest
