What information should I gather before reporting error code 1200 (unk) to Janitor AI support?

Before contacting support, gather the exact timestamp of the error, the full request payload you sent (without revealing your API key directly), the complete error response received, the specific API endpoint being called, the LLM model you were attempting to use, and details about your client environment (e.g., programming language, library version, browser). Steps to reproduce the error are also highly valuable.
