Recommended action: Inspect client.get_collection(name).config.params and pass matching vector_name ('' for unnamed) and sparse_vector_name; upgrade langchain-qdrant if the sparse name is dropped on reload.
Option: Pass vector names that match the collection config [evidence: official_recommended_action]
Applies when: Collections created outside LangChain or with custom names
Steps:
1. info = client.get_collection(name); inspect info.config.params.vectors and sparse_vectors
2. QdrantVectorStore(client=client, collection_name=name, embedding=emb, vector_name='<name or empty>', sparse_vector_name='<name>', retrieval_mode=...)
Expected: Validation passes.
Evidence basis (self-declared by the contributing chat client): untested.
