[Bug]: aws_emr_cluster Inappropriate value for attribute "configurations": string required.

Terraform Core Version

1.9.8

AWS Provider Version

5.69.0

Affected Resource(s)

While working with EMR, I followed the Terraform guide but encountered an error: Incorrect attribute value type about configurations in aws_emr_cluster.

Could you please confirm this? I would prefer to use this option as it's more readable than configurations_json.

Expected Behavior

working well

Actual Behavior

Incorrect attribute value type occured
