memory_hybrid_search: query cannot be empty

Error message

memory_hybrid_search: query cannot be empty

What it means

Empty-value guard in the memory_hybrid_search tool's execute: the deserialized `query` was blank/empty. The hybrid search fuses vector, lexical and graph signals, none of which are meaningful for an empty query, so it is refused before any retrieval; supply a non-empty query string.
