- Fix TypeScript error in ConverseStreamCommand payload
- Add proper JSON parsing for test stream events
- Improve error handling with proper Error objects
- Add test-specific model info with required fields
- Fix cross-region inference and prompt cache config
Problem:
The current Bedrock implementation uses the Bedrock SDK, which requires separate handling for different model types and doesn't provide a unified streaming interface.
Solution:
Integrate the Bedrock Runtime API to provide a single, unified interface for all Bedrock models (Claude and Nova) using the ConverseStream API. This eliminates the need for separate handlers while maintaining all existing functionality.
Key Changes:
- Refactored AwsBedrockHandler to use @aws-sdk/client-bedrock-runtime
- Enhanced bedrock-converse-format.ts to handle all content types and properly transform between Anthropic and Bedrock formats
- Maintained cross-region inference support with proper region prefixing
- Added support for prompt caching configuration
- Improved AWS credentials handling to better support default providers
- Added proper error handling and token tracking for all response types
Dependencies:
- Added @aws-sdk/client-bedrock-runtime for unified API access
- Removed @anthropic-ai/bedrock-sdk dependency
Testing:
- Verified message format conversion for all content types
- Tested cross-region inference functionality
- Validated streaming responses for both Claude and Nova models
This change simplifies the codebase by providing a single, consistent interface for all Bedrock models while maintaining full compatibility with existing features.
Change:
const urlHost = new URL(this.options.openAiBaseUrl).host;
To:
const urlHost = new URL(this.options.openAiBaseUrl ?? "").host;
because the nullish coalescing operator (??) to default to an empty string if this.options.openAiBaseUrl is undefined.
It ensures that the URL constructor always receives a valid string.
