nmslib
A library or engine type explicitly named as invalid for OpenSearch Serverless vector indexes.
- ValidationException: The OpenSearch Serverless engine type associated with your vector index is invalid.
Recreate the OpenSearch Serverless vector index with "engine": "faiss" instead of "nmslib" in the storage configuration, then retry the CreateKnowledgeBase call. FAISS is the only accepted engine type now.
