Hey everyone,
I am facing an issue with the
KnowledgeGraphQueryEngine
. So whenever I am trying to run a query using the
KnowledgeGraphQueryEngine
, I am continuously getting this error:
pydantic.v1.error_wrappers.ValidationError: 1 validation error for LLMPredictStartEvent
template
none is not an allowed value (type=type_error.none.not_allowed)
And here's the code snippet:
query_engine = KnowledgeGraphQueryEngine(
storage_context=storage_context,
llm=llm,
verbose=True,
)
response = query_engine.query("Tell me about Peter Quill?")
Any help will be appreciated! Thanks in advance.
P.S. I am using Neo4JGraphStore instead of NebulaGraph.
