Claude Code Citation Format Validation Error in AWS Bedrock Integration

Bug Description
Claude Code + AWS Bedrock Integration Error - Citation Format Issue
I'm experiencing a persistent error when using Claude Code with AWS Bedrock that's blocking my workflow.
After Claude Code ingests code repositories, I consistently receive this error:

⎿ Error: API Error: messages.27.content.0.text.citations: Extra inputs are not permitted


  ⎿  API Error: messages.39.content.0.text.citations: Extra inputs are not permitted

  ⎿  API Error: messages.13.content.0.text.citations: Extra inputs are not permitted

Steps to Reproduce:

Start Claude Code session with AWS Bedrock as backend
Ingest code repository/files (specifically django ninja with some mypy bash output)
After ingestion completes, attempt to interact with Claude Code
Error occurs in message # 27 of the conversation
