orchestrata_ultimate.semantic_graph.exceptions

Reference › orchestrata_ultimate › semantic_graph › exceptions

The exception hierarchy of the semantic graph package. Everything derives from SemanticGraphError: ConnectionError (the backing store cannot be reached; it shadows the builtin name inside this package), QueryError (a graph query failed), EntityNotFoundError and VectorSearchError (vector similarity search failed). The Memgraph adapter, rerankers and the package facade import it. The classes carry no extra fields.
