I am trying to deploy a container using GitHub actions

But it is failing in the following step

- name: Push the Docker Image to lightsail
    env: 
      IMAGE_SHA_TAG: ${{ github.sha }}
      IMAGE_URL: ${{ vars.LIGHTSAIL_IMAGE }}:${{ github.sha }}
    run: >
      aws lightsail push-container-image
      --region ${{ vars.AWS_REGION }}
      --service-name ${{ vars.SERVICE_NAME }}
      --label git-push
      --image $IMAGE_URL

It seems that the colon is making this command break because in the output I get

Unknown options: :da39a3ee5e6b4b0d3255bfef95601890afd80709

I replaced this step

- 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

But I keep getting the same error
