[ ] I checked the documentation and related resources and couldn't find an answer to my question.

I am using llama index with azure open ai to evaluate
When I am calling evaluate function with query engine,llm,dataset I am getting attribute error mentioning 'float' object has no attribute "response error" with an exception raised in job[1]: AttributeError('NoneType' object has no attribute 'search')

from ragas.integrations.llama_index import evaluate

Result=evaluate (query_engine,metrics,dataset)
