ValueError: Evaluation LLM outputted an invalid JSON. Please use a better evaluation model.

Problem: When I use the local Llama-7b model for faithfulness calculation, the following error occurs. Is it because this metric does not support models with smaller parameters? It only supports closed-source LLMs, such as gpt3.5?

Hello, I've been experiencing the same issue, except I'm using an Azure OpenAI instance.

Have you had any luck in solving this?

I am also getting the same error with Azure OpenAI.

Can someone help me to get rid of this error.?

Can better support for Azure Open AI be added please?
