[0.4.7]

Added

  • MCP Integration Cross-Region Support for QuickSuite Integration
    • Added cross-region support for QuickSuite integration enabling MCP connectivity across multiple AWS regions: us-east-1, us-west-2, eu-west-1, ap-southeast-2

Fixed

  • Stack deployment failure due to MCP Integration IAM Permissions - GitHub Issue #154

    • Fixed missing permissions in AgentCoreGatewayManagerFunctionRole by creating the AgentCoreGateway execution role explicitly in the CloudFormation template instead of dynamically in the Lambda function

  • Post-Processing Lambda Hook Compression Handling - GitHub Issue #155

    • Added intermediate decompression lambda to handle document decompression before invoking custom post-processing lambdas
    • Root Cause: After introducing document compression, the post-processing lambda hook was receiving compressed documents in the EventBridge payload, forcing external lambdas to import idp_common package and handle decompression manually
    • Solution: New PostProcessingDecompressor lambda function intercepts EventBridge events, decompresses documents using Document.load_document(), and invokes custom post-processors with decompressed payload
    • Benefits: Maintains backward compatibility, eliminates external dependencies (no idp_common import needed), keeps compression/decompression logic encapsulated within IDP stack, minimal performance impact (<1s latency)

  • Enhanced Bedrock Error Handling for Agent Companion Chat

    • Implemented robust error handling system for Bedrock API errors in Agent Companion Chat feature with automatic retry and graceful degradation
    • Automatic Retry with Exponential Backoff: Configured boto3 with adaptive retry mode (3 attempts) and exponential back-off to prevent service overload
    • User-Friendly Error Messages: Created BedrockErrorMessageHandler to convert technical errors into clear, actionable messages for service unavailable (503), throttling (429), access denied (403), validation errors (400), timeouts (408), and quota exceeded scenarios
    • Sub-Agent Error Handling: When sub-agents (Analytics, Error Analyzer, Code Intelligence) encounter Bedrock errors, the orchestrator continues gracefully without crashing, only displaying the first error to avoid duplicates while allowing other sub-agents to complete

  • GovCloud Template Generation - Missing AppSync and MCP Resource Removal

    • Fixed CloudFormation deployment error "Unresolved resource dependencies [DeleteDocumentResolverFunction]" when deploying GovCloud templates
    • Test Studio Resources Added (36 resources): Added all Test Studio Lambda functions, AppSync resolvers, data sources, and supporting infrastructure to removal list (DeleteTestsResolver, TestRunnerResolver, TestResultsResolver, TestSetResolver, and all related functions, queues, and policies)
    • MCP/AgentCore Gateway Resources Added (7 resources): Added MCP integration resources that depend on Cognito UserPool to removal list (AgentCoreAnalyticsLambdaFunction, AgentCoreGatewayManagerFunction, AgentCoreGatewayExecutionRole, AgentCoreGateway, ExternalAppClient)
    • MCP Outputs Removed (8 outputs): Removed MCP-related outputs that reference deleted resources (MCPServerEndpoint, MCPClientId, MCPClientSecret, MCPUserPool, MCPTokenURL, MCPAuthorizationURL, DynamoDBAgentTableName, DynamoDBAgentTableConsoleURL)
    • EnableMCP Default Changed: Set EnableMCP parameter default to 'false' for GovCloud since MCP integration requires Cognito authentication infrastructure
    • Impact: GovCloud templates now deploy successfully without dependency errors, maintaining core document processing functionality in headless mode
