I am trying to access my model using ChatHuggingFace(llm=llm), however it is giving constant error. I have added images for details.  
I have access to the particular model as I am able to access it using langchain chains but there is some problem with ChatHuggingFace it seems.  
Please help!

</div>

Here is the code:  
from langchain\_core.messages import (  
HumanMessage,  
SystemMessage,  
)  
from langchain\_huggingface import ChatHuggingFace

messages = [  
SystemMessage(content=“You’re a helpful assistant”),  
HumanMessage(  
content=“What happens when an unstoppable force meets an immovable object?”  
),  
]

chat\_model = ChatHuggingFace(llm=llm)
