Problem deleting a directory on S3 - Missing required header for this request: Content-MD5

[climmmm]

Bug Report

Q	A
Flysystem Version	3.29.1
Adapter Name	aws-s3-v3
Adapter version	3.29.0

Summary

Since the last update of the "aws/aws-sdk-php" package (3.337.3), when we use the 'deleteDirectory' function, we get the following error: <Error><Code>InvalidRequest</Code><Message>Missing required header for this request: Content-MD5</Message><Resource>/s3app-xxxxxxxxx?delete</Resource><RequestId>xxxxxxxxx</RequestId></Error>"

We had to downgrade the aws version to 3.336.6 to avoid this error.

According to ChatGPT, this is due to the latest update of the "aws/aws-sdk-php" package, which no longer automatically adds the Content-MD5 header.

How to reproduce

Update "aws/aws-sdk-php" package to version 3.337.3 and try to delete directory with the library flysystem on S3.

Thank you in advance for your help
