Pull request overview
Adjusts LanguageModelFailurePlugin request parsing and prompt injection to better handle OpenAI-style payloads by changing how request bodies are decoded/serialized and by updating the injected message role.
Changes:
- Decode request body bytes to a string for OpenAI request detection/parsing (instead of using
request.BodyString). - Add Debug logs for request encoding, original body, and modified body prior to rewriting the request.
- Change injected prompt role from
"user"to"system"for chat-completions and Responses API requests.
