Introduce `Filter` rules in the payload configuration to remove specified JSON paths from the payload. Update related helper functions and add examples to `config.example.yaml`.
- Add ErrorLogsMaxFiles config field with default value 10
- Support hot-reload via config file changes
- Add Management API: GET/PUT/PATCH /v0/management/error-logs-max-files
- Maintain SDK backward compatibility with NewFileRequestLogger (3 params)
- Add NewFileRequestLoggerWithOptions for custom error log retention
When request logging is disabled, forced error logs are retained up to
the configured limit. Set to 0 to disable cleanup.
- Modified extractKiroTokenData to support both Attributes and Metadata sources
- Fixes issue where JSON file-based tokens were not being read correctly
- FileSynthesizer stores tokens in Metadata, ConfigSynthesizer uses Attributes
- Now checks Attributes first (config.yaml), falls back to Metadata (JSON files)
- Ensures dynamic model fetching works for all Kiro authentication methods
- Prevents fallback to static model list that incorrectly includes opus for free accounts
Kiro API endpoints only exist in us-east-1, but OIDC region can vary
by Enterprise user location (e.g., ap-northeast-2 for Korean users).
Previously, when ProfileARN was not available, the code fell back to
using OIDC region for API calls, causing DNS resolution failures:
lookup codewhisperer.ap-northeast-2.amazonaws.com: no such host
This fix removes the OIDC region fallback for API endpoints.
The region priority is now:
1. api_region (explicit override)
2. ProfileARN region
3. us-east-1 (default)
Fixes: Issue #253 (200-400x slower response times due to DNS failures)
Switch from CodeWhisperer endpoint to Amazon Q endpoint for all auth types:
- Use q.{region}.amazonaws.com/generateAssistantResponse as primary endpoint
- Works universally across all AWS regions (CodeWhisperer only exists in us-east-1)
- Use application/json Content-Type instead of application/x-amz-json-1.0
- Remove X-Amz-Target header for Q endpoint (not required)
- Add x-amzn-kiro-agent-mode: vibe header
- Add x-amzn-codewhisperer-optout: true header
- Keep CodeWhisperer endpoint as fallback for compatibility
This change aligns with Amazon's consolidation of services under the Q branding
and provides better multi-region support for Enterprise/IDC users.
Introduce a custom HTTP client utilizing utls with Firefox TLS fingerprinting to bypass Cloudflare fingerprinting on Anthropic domains. Includes support for proxy configuration and enhanced connection management for HTTP/2.
Address @Xm798's feedback: OIDC region may differ from API region in some
Enterprise setups (e.g., OIDC in us-east-2, API in us-east-1).
Region priority (highest to lowest):
1. api_region - explicit override for API endpoint region
2. ProfileARN - extract region from arn:aws:service:REGION:account:resource
3. region - OIDC/Identity region (fallback)
4. us-east-1 - default
Changes:
- Add extractRegionFromProfileARN() to parse region from ARN
- Update getKiroEndpointConfigs() with 4-level region priority
- Add regionSource logging for debugging
