Fix UnsupportedParamsError
in LiteLLM
✅ Solution
The "UnsupportedParamsError" in LiteLLM arises when a model is called with parameters it doesn't recognize. To fix this, either remove the unsupported parameters from your API call or ensure that the model deployment is configured correctly to handle the parameters you are sending by checking the specific model's documentation on supported parameters. Also, ensure your LiteLLM version is up-to-date, as newer versions might include parameter compatibility fixes or model updates.
