I am getting this error. I am performing RAG on meta-llama/Llama-2-7b-chat-hf, few days ago the same code was working fine. I tried with str(query_wrapper_prompt) the model gets downloaded but I can't perform query_engine.query(). 1st image - when I keep query_wrapper_prompt as it is. 2nd image - after applying str(query_wrapper_prompt)
