Resource not defined when no functions present #96

Closed srdcarrion closed 1 year ago

srdcarrion commented 2 years ago

I want to deploy just layers. I.e. no functions or resources included. When doing so this error fires:

The CloudFormation template is invalid: Template format error: At least one Resources member must be defined.

On review of the template in ./.serverless/ there is no resources. I can only get around this by adding a dummy resource to the serverless.yaml:

resources:
  Resources:
    NullResource:
      Type: AWS::CloudFormation::WaitConditionHandle

I'd expect to see a "AWS::Lambda::LayerVersion" resource type.

Any reason why this might be the case?

Yeah, the serverless itself validates if you have at least one resource to deploy (it is not related to this plugin).
