Fix BadRequestError
in LiteLLM
✅ Solution
BadRequestError in litellm generally stems from invalid data being sent to the LLM provider's API. Fix this by carefully validating the inputs to the `litellm.completion` or `litellm.embedding` calls, ensuring data types, prompt formatting, and parameter values conform to the provider's API specifications (especially message roles and content). If using functions, double-check function call structures.
