Image URI not passing between build and deploy jobs in GitHub Actions ECS workflow

[sandeeptf]

Issue Description

The image URI is not being passed correctly between the build and deploy jobs in our ECS deployment workflow. While the image is successfully built and pushed in the build job, the deploy job receives an empty image URI.

Current Behavior

• Build job successfully creates and pushes image with URI format: [account-id].dkr.ecr.[region].amazonaws.com/[repository]:mysql-latest-[timestamp]
• Build job output shows correct image URI: ***.dkr.ecr.us-east-1.amazonaws.com/***-ecr:mysql-latest-20250128065643
• Deploy job receives empty image URI, causing deployment to fail

Expected Behavior

• Deploy job should receive the complete image URI from the build job
• Task definition should be updated with the correct image URI
• Deployment should proceed with the newly built image

Did you echo the image URI into the github output? Following the steps from https://github.com/aws-actions/amazon-ecs-deploy-task-definition, do you have this command in the build step: echo "image=$ECR_REGISTRY/$ECR_REPOSITORY:$IMAGE_TAG" >> $GITHUB_OUTPUT

- name: Build, tag, and push image to Amazon ECR
      id: build-image
      env:
        ECR_REGISTRY: ${{ steps.login-ecr.outputs.registry }}
        ECR_REPOSITORY: my-ecr-repo
        IMAGE_TAG: ${{ github.sha }}
      run: |
        docker build -t $ECR_REGISTRY/$ECR_REPOSITORY:$IMAGE_TAG .
        docker push $ECR_REGISTRY/$ECR_REPOSITORY:$IMAGE_TAG
        echo "image=$ECR_REGISTRY/$ECR_REPOSITORY:$IMAGE_TAG" >> $GITHUB_OUTPUT # output to 

    - name: Fill in the new image ID in the Amazon ECS task definition
