Symptoms

Using AWS CLI 2.23.0 and later versions, for example for PutBucketLifecycleConfiguration or PutBucketReplication against an ECS results in an error like the following:

"An error occurred (InvalidRequest) when calling the PutBucketLifecycleConfiguration operation: Missing required header for this request: Content-MD5"

Example:

aws --version
aws-cli/2.24.1 Python/3.12.6 Linux/5.15.167.4-microsoft-standard-WSL2 exe/x86_64.ubuntu.24

aws --profile=Gen3 --endpoint-url=http://X.X.X.X:9020 s3api put-bucket-lifecycle-configuration --bucket bkt_01 --lifecycle-configuration file://lifecycle_01.json

An error occurred (InvalidRequest) when calling the PutBucketLifecycleConfiguration operation: Missing required header for this request: Content-MD5

Cause

A change in AWS CLI 2.23.0 (and later versions) uses a new checksum algorithm by default for S3 operations. 
AWS CLI now uses x-amz-sdk-checksum-algorithm: CRC64NVME

Resolution

Use AWS CLI versions earlier than version 2.23.0 or other S3 clients. ECS CRC64NVME support will be provided in a future release.
