[BUG] Deleting agent vector stores leave empty AI Search indexes. #51447
Description
Library name and version
Azure.AI.Projects 1.0.0-beta.10
Describe the bug
I use the Azure AI Foundry Agent service with the Standard setup, with Bring Your Own (BYO) resources configured for threads, files, and vector stores. When I create a vector store and add files, it creates an index in the connected Azure AI Search instance.
PersistentAgentsVectorStore vectorStore =
await agentsClient.VectorStores.CreateVectorStoreAsync(
fileIds: myFileIds,
name: "my-vector-store",
expiresAfter: new VectorStoreExpirationPolicy(
VectorStoreExpirationPolicyAnchor.LastActiveAt,
7
),
cancellationToken: cancellationToken
);
When I delete the vector store, the vector store is deleted, but the associated index in Azure AI Search doesn't get removed. The index document count goes to 0 and total storage size goes to 0, but it never gets deleted.
await agentsClient.VectorStores.DeleteVectorStoreAsync(
"my-vector-id",
cancellationToken: cancellationToken
);
Should this get removed as well? What is the proper way to clean up the index since there is a limit to the number of indexes an AI Search can have?
Expected behavior
I expect the AI Search index to also be removed so we don't run out of quota space.
Actual behavior
The AI Search index is emptied, but not removed.
Reproduction Steps
PersistentAgentsVectorStore vectorStore =
await agentsClient.VectorStores.CreateVectorStoreAsync(
fileIds: myFileIds,
name: "my-vector-store",
expiresAfter: new VectorStoreExpirationPolicy(
VectorStoreExpirationPolicyAnchor.LastActiveAt,
7
),
cancellationToken: cancellationToken
);
await agentsClient.VectorStores.DeleteVectorStoreAsync(
"my-vector-id",
cancellationToken: cancellationToken
);
Environment
No response
