I am executing a GitHub action to push a Docker image into AWS ECR and Lightsail.
While pushing into ECR works, it fails silently in the following block.

  - name: Push the Docker Image to lightsail
    env: 
      IMAGE_SHA_TAG: ${{ github.sha }}
      IMAGE_URL: ${{ format('{0}{1}{2}', vars.LIGHTSAIL_IMAGE ,':', github.sha) }} 

    run: >
      aws lightsail push-container-image
      --region ${{ vars.AWS_REGION }}
      --service-name ${{ vars.SERVICE_NAME }}
      --label git-push
      --image $IMAGE_URL

In the log, the command doesn’t throw any error.

But after running the following block, The LIGHTSAIL_DOCKER_IMAGE is empty.

- name: Save updated LIGHTSAIL_IMAGE_TAG 
        run: |
          echo "LIGHTSAIL_DOCKER_IMAGE=$(aws lightsail get-container-images --service-name ${{ vars.SERVICE_NAME }} --region ${{ vars.AWS_REGION }} | jq -r .containerImages[0].image)"  >> $GITHUB_ENV
          echo "LIGHTSAIL_DOCKER_IMAGE=$LIGHTSAIL_DOCKER_IMAGE"

If I execute locally

aws lightsail get-container-images --service-name ${{ vars.SERVICE_NAME }} --region ${{ vars.AWS_REGION }}

I get

{
    "containerImages": []
}
