awslabsbedrock_kb_retrieval_mcp_server did not pass base id correctly.

### Describe the bug

I have configured mcp server with q cli, when it queries kb server it keeps asking me to input kb id, but i have configured the id in my mcp server already. I also added tag mcp-multirag-kb=true to the kb. Can anyone help?

> pls search it by my knowledge base first
I'll search for EKS cluster security best practices using your knowledge base first. Let me do that for you.

🛠️ Using tool: QueryKnowledgeBases from mcp server awslabsbedrock_kb_retrieval_mcp_server

● Running QueryKnowledgeBases with the param:

my mcp config
