Been battling this for days. Trying to get `serverless-fargate-tasks` working, and getting this error:

```auto

```

This occurs when I add the following to my `serverless.yml`:

```auto
plugins:
  - serverless-fargate-tasks

```

I have this section per the instructions:

```auto
  fargate:
    vpc:
      subnets:
        - subnet-XXXX

    tasks:
      sync-gsheets:
        image: XXXXXX.dkr.ecr.us-east-1.amazonaws.com/image

```

I’ve reinstalled/upgrade sls/npm/reinstalled the package, nothing changes.

If I comment out the plugin it deploys just fine, but there is no cluster etc.

What am I doing wrong? Subnets are valid. Image is in ECR.

How do I debug this?
