Bedrockナレッジベースの削除について

Incident I created a knowledge base in Bedrock. After using it, I tried to delete it, but the following message appeared. "Delete unsuccessful Unable to delete data from vector store for data source with ID 6QE7HU8OXH. Check your vector store configurations and permissions and retry your request. If the issue persists, consider updating the dataDeletionPolicy of the data source to RETAIN and retry your request." The "collection" in Amazon OpenSearch Service was deleted. The S3 bucket was already deleted. After setting Knowledge Base/Data Source/Advanced Settings/Data deletion policy to "Retain", I tried to delete it again, but it was not possible to delete it.

Background In the reference book and website, after building a verification environment in Bedrock, it was recommended to first delete the knowledge base in Bedrock, then delete the Opensearch collection, and then delete the S3 bucket. I may have overlooked the instructions here and deleted the S3 bucket first.

Points I don't understand: ・I don't know what specific service "data from vector store for data source with ID 6QE7HU8OXH" refers to, or how to access it. ・I don't know what specific service "vector store configurations" refers to, or how to access it.

Currently, it doesn't seem like I'm being charged, but I would like to resolve the "Delete unsuccessful" message that keeps appearing in the Bed rock knowledge base status.

I would appreciate any advice you can give me. Thank you in advance.

発生事象 Bedrockでナレッジベースを作成。使用後、削除を試みたが以下のメッセージがでた. "Delete unsuccessful Unable to delete data from vector store for data source with ID 6QE7HU8OXH. Check your vector store configurations and permissions and retry your request. If the issue persists, consider updating the dataDeletionPolicy of the data source to RETAIN and retry your request." Amazon OpenSearch Serviceでの"コレクション"は削除。 S3のバケットは既に削除。 ナレッジベース/データソース/詳細設定/Data deletion policyを"Retain"に設定後、再度削除を試みたが、削除にできなかった。

経緯 参考書籍およびサイトではBedrockでの検証環境構築後、まずBedrockでのナレッジベースを削除し、その後Openserchのコレクション削除、S3のバケット削除の順番で作業を進めるようになっていた。 私はここの指示手順を見落とし、先にS3バケットを削除してしまった可能性がある。

不明点 ・” data from vector store for data source with ID 6QE7HU8OXH”が具体的にどのサービスのどこを指すのか、そこへのアクセスが分からない。 ・”vector store configurations”具体的にどのサービスのどこを指すのか、そこへのアクセスが分からない。

現状 課金は発生していないようであるが、Bed rock ナレッジベースのステータスに"Delete unsuccessful"が表示されつつけるのを解消したい。

ご助言いただければ幸いです。 よろしくお願いいたします。
