Hi,

I am trying to migrate from in-house Jenkins to GitHub actions for our CI-CD pipelines.
I have created an ‘action.yml’ file in the ‘.github/workflows/’ folder.
The job builds 2 separate docker containers, tagging them both twice and then pushing to AWS ECR which all works fine.

The error I am getting is from the below:

 Deploy_to_ECS:
    name: Deploy to ECS
    runs-on: ubuntu-latest
    needs: [Build_Push_Docker_Images]
    steps:
      - uses: actions/checkout@v2
  - name: Get short SHA
    id: slug
    run: echo "::set-output name=sha7::$(echo ${GITHUB_SHA} | cut -c1-7)"

  - name: Render Amazon ECS task definition for php-fpm container
    id: render-php-container
    uses: aws-actions/amazon-ecs-render-task-definition@v1
    with:
      task-definition: task-definition.json
      container-name: "php-fpm"
      image: "${{ env.AWS_ACCOUNT_ID }}.dkr.ecr.${{ env.AWS_DEFAULT_REGION }}.amazonaws.com/${{ env.IMAGEPHPFPM }}:${{ steps.slug.outputs.sha7 }}"

The error I get is: /home/runner/work/the-first/the-first/task-definition.json: Unexpected token � in JSON at position 0
The file is valid json, I have checked over and over again and I am at a loss on how to proceed. Using normal aws cmd line tools with this task-definition.json file successfully registers a new task definition in ECS.
Debug logs don’t shed any more light on the situation either.
Any help would be much appreciated.

Thanks,
Terry
