With the following serverless.yml file:

  hello:
    handler: handler.hello
    events:
    - stream:

          - AttributeName: foo
            AttributeType: S

plugins:
- "serverless-localstack"

custom:
  localstack:
    stages:
      - "local"
```
It fails with a generic error (500) on the deployment end and with `:ERROR:localstack.services.cloudformation.cloudformation_starter: Unable to parse and create resource "HelloEventSourceMappingDynamodbFooTable": 'NoneType' object has no attribute 'function_arn'` on the localstack end.
It deploys fine to AWS.
