Cannot read property 'type' of null

Followed all steps of the deployment process outlined in the default Github Actions yml. This step always ends in a null pointer exception, and since index.js is so massive, it’s hard to debug anything. The error is also only as verbose as the title, no stacktrace, line numbers, anything.

There is not an API that will give you the task definition in the input format. This command will generate the skeleton to start off with: aws ecs register-task-definition --generate-cli-skeleton > task-definition.json

Based on the logs above, it looks like you’re now able to register the task definition but ECS is not able to start your containers. For next steps, I would suggest looking at the service in the ECS console, going to Tasks -> Stopped to see why the containers are dying.

Yeah, please open a separate issue.

If you’re able to reproduce the initial issue, I have some additional debugging turned on in my fork that should give us a stacktrace:

    - name: Deploy Amazon ECS task definition
      uses: clareliguori/amazon-ecs-deploy-task-definition@master
      with:
