🍹 The Update for mottych/purposepath-coaching-api/preprod (at a6b50d1) was successful.

✨ Neo Explanation

This update deploys a new version of the coaching API to the preprod environment by swapping the Lambda function to a freshly built Docker image. No infrastructure changes are involved — only the application code running inside the container is being updated.

Root Cause Analysis

A new version of the coaching API Docker image has been built and is being deployed to the preprod environment. The build was triggered with a fresh BUILD_TIMESTAMP, indicating a CI/CD pipeline run that produced a new container image with a different content digest.

Dependency Chain

A new Docker image (coaching-image) was built from the coaching service Dockerfile → pushed to ECR with a new SHA256 digest → the Lambda function (coaching-api) is updated to point to the new image URI. All other infrastructure (DynamoDB tables, API Gateway, domain config) remains untouched.

Risk analysis

No stateful resources are being replaced or deleted. This is a straightforward Lambda container image swap in preprod, with 21 resources unchanged.
