When does this happen?

IF ERROR:root:Failed to get supported params: argument of type 'NoneType' is not iterable when using the LLM class in crewAI

How others solved it

THEN Format the model name as 'provider/llm-name' (e.g., 'groq/llama3-8b-8192') when instantiating the LLM class. This ensures the provider is correctly parsed by LiteLLM. Avoid using plain model names without a provider prefix.

llm = LLM(model="groq/llama3-8b-8192", api_key=GROQ_API_KEY)
