Hello guys, i used below code.

rerank = SentenceTransformerRerank(
model="cross-encoder/ms-marco-MiniLM-L-2-v2", top_n=3
)
response_synthesizer = get_response_synthesizer(streaming=True)
try:
vector_retriever = self._vector_index.as_retriever(
similarity_top_k=10)
keyword_retriever = self._keyword_index.as_retriever()
custom_retriever = CustomRetriever(
vector_retriever, keyword_retriever)
custom_query_engine = RetrieverQueryEngine(
retriever=custom_retriever, response_synthesizer=response_synthesizer, node_postprocessors=[rerank])
response = custom_query_engine.query(query)
answer = generatorize_response(response.response_gen)

But getting the error :
tenacity.RetryError: RetryError[<Future at 0x7c4b17a48610 state=finished raised APIRemovedInV1>]

in this line of execution(response = custom_query_engine.query(query).
