切り分け

• reconfigureの実行

 terraform -chdir=cdktf.out/stacks/sample_auroracluster init -reconfigure

→ 解消せず

解消方法

state rm してからimportすると解消するらしいとのことで実施

aws-vault exec goals-myabaou -- terraform -chdir=cdktf.out/stacks/sample_auroracluster state rm aws_cloudwatch_event_rule.rdsEventRule

Removed aws_cloudwatch_event_rule.rdsEventRule
Successfully removed 1 resource instance(s).

• import

	aws-vault exec goals-myabaou -- terraform -chdir=cdktf.out/stacks/sample_auroracluster import aws_cloudwatch_event_rule.rdsEventRule default/sample-aurora-recreate
aws_cloudwatch_event_rule.rdsEventRule: Importing from ID "default/sample-aurora-recreate"...

Import successful!

The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.

その後diff確認し No changes. Your infrastructure matches the configuration.
となることを確認。

少々解せないが解消したのでよしとする。　GitHubActionsで実行した後にtfstateに破壊的な何か変更があったのかもしれない。
