When does this happen?
IF When using a non-Anthropic model (e.g., vercel_ai_gateway) with the 'thinking' parameter enabled, LiteLLM returns a 500 error indicating the parameter is unsupported.
How others solved it
THEN Configure LiteLLM to either drop unsupported parameters by setting 'litellm.drop_params=True' in the proxy configuration, or explicitly allow the 'thinking' parameter by sending 'allowed_openai_params=['thinking']' in the request. For the proxy, add 'drop_params: true' under 'litellm_settings' in the config.
litellm_settings: drop_params: true
