Fix BadRequestError

✅ Solution

BadRequestError in CrewAI often arises from incorrect API key setup, missing required parameters like `max_tokens` or `model` in the LLM configuration, or exceeding rate limits of the LLM provider. Verify the API key is correctly set in the `os.environ`, ensure crucial parameters are set as defined by the used model (e.g., `max_tokens` for GPT models), and implement retry mechanisms with exponential backoff for handling rate limits. Consider using a validation mechanism for your LLM configuration before using it to catch errors before they occur.
