I am getting an AuthenticationError where LlamaIndex is looking for the OpenAI key, however I have setup a HuggingFaceLLM, passed it to ServiceContext, and passed the ServiceContext to the VectorStoreIndex.from_vector_store() constructor. I am then initializing the query engine as follows:
query_engine = PodClip_index.as_query_engine()
response = query_engine.query("What is Weaviate?")
Can you help me understand why I am getting this AuthenticationError for the OpenAI key?
