Hi @biswanathmukherjee 👋 Friendly nudge — this pattern is ready for review. Deployed and tested end-to-end on a live AWS account. Would appreciate a look when you have time. Thank you! |
The InvokeAgent API returns a streaming response that the AWS CLI does not support. Replaced with Python SDK snippet that correctly handles the event stream.
