<!-- A clear and concise description of the bug -->
I use Claude Code for CR. And use the api with the LLM openapi in my company. And the business service is provided by AWS.
I meet a error in the code review situation, I want to know if it is bacause the my company openapi has something wrong. Because I can use it with AWS Bedrock perfectly. Could you help me find the bugs?
