I am facing following error everytime i use tools(query_engine_tools) in Openaiassiatantagent

LocalProtocolError Traceback (most recent call last)
LocalProtocolError: Illegal header value b'Bearer '

The above exception was the direct cause of the following exception:

APIConnectionError Traceback (most recent call last)
/usr/local/lib/python3.10/dist-packages/openai/_base_client.py in _request(self, cast_to, options, remaining_retries, stream, stream_cls)

896 )
--> 897 raise APIConnectionError(request=request) from err

899 return self._process_response(

APIConnectionError: Connection error.

I am getting the following error when I try running Neo4jGraphStore()

""
ValueError: Could not use APOC procedures. Please ensure the APOC plugin is installed in Neo4j and that 'apoc.meta.data()' is allowed in Neo4j configuration
""

I am getting Neo4jGraphStore import error.

from llama_index.graph_stores import Neo4GraphStore

It works on Google colab but not on my machine.

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)

Any help is appreciated!
Thank you 🙂.
