Terraform error while updating a cross-region replica broker "Global broker attribute [Optional[engineVersion]] cannot be modified in Replica broker directly." while engine_version is required field in the aws_mq_broker resource

I use the below resource to provision a primary broker along with a replica broker in another region. The update to the primary broker goes through fine but the replica broker update fails with "Global broker attribute [Optional[engineVersion]] cannot be modified in Replica broker directly.". Given the engine_version is a required field in aws_mq_broker resource, I can't get rid of it for when I update the replica.

Terraform Core Version

">= 1.3.0"

AWS Provider Version

"~> 5.42"

Affected Resource(s)

Resource: aws_mq_broker

Expected Behavior

Update the replica broker even though the engine version is specified.

Actual Behavior

Plan erros with: Error: updating MQ Broker (b-aff7b593-111d-437e-93cb-be17c0e75dd5) configuration: operation error mq: UpdateBroker, https response error StatusCode: 400, RequestID: b4477a83-f7a1-4bdd-b950-db7e5a92e666, BadRequestException: Global broker attribute [Optional[engineVersion]] cannot be modified in Replica broker directly.
