Start with the configuration entries shown in the issue and the latest requirements.txt, then reproduce the failure on Windows using minimax-2.7 and capture the missing terminal traceback. Compare the configured API URL and model name with the project's supported model/API handling; done means the configuration works or the issue documents the exact incompatibility and required change.
