Defining Agent in LLamaIndex and Mistral 7B is throwing Attribute error

Question

I am using llamaIndex and locally downloaded Mistral model (mistral-7b-instruct-v0.2.Q4_K_M.gguf). I have created the python binding for this model using "llama-cpp". On defining the agent using:

'''

worker1 = FunctionCallingAgentWorker.from_tools([query_engine_tool], llm=llm, verbose=True,allow_parallel_tool_calls=True,)

'''

But on executing it I am getting the following error:

AttributeError                            Traceback (most recent call last)
Cell In[43], line 2
      1 # define Agent and agent service
----> 2 worker1 = FunctionCallingAgentWorker.from_tools(
      3     [query_engine_tool], llm=llm, verbose=True,allow_parallel_tool_calls=True,
      4 )

AttributeError: 'LlamaCPP' object has no attribute 'model'

I am doing the development using python. Any help will be highly appreciated.
