Extend Serverless validation schema with the plugin options

I am using the follow plugins;

plugins:
  - serverless-pseudo-parameters
  - serverless-offline
  - serverless-dynamodb-local
  - serverless-plugin-warmup

And have warm on my function.

functions:
  RestAPI:
    name: "${self:custom.myServiceName}"
    handler: lambda.handler
    memorySize: 128
    timeout: 30
    description: REST API
    events:
      - http:
          method: ANY
          path: /
      - http:
          method: ANY
          path: /{proxy+}
    warmup:
      enabled: true
    environment:
      NODE_ENV: ${self:custom.myStage}

Any ideas why this isn’t working? It worked before. But now I get this warning in the console everytime I deploy.

Serverless: Configuration warning at 'functions.RestAPI': unrecognized property 'warmup'
Serverless:  
Serverless: Learn more about configuration validation here: http://slss.io/configuration-validation

Hi @gruckionvit

Reading the link in that warning, it seems that serverless has started to apply schema validation. So now plugins should provide a JSON-schema of their params. No idea of when did that happened… I’ve been going through their release notes but couldn’t find anything. Anyway, it’s not harmful. It’s just a warning meaning that the plugin should provide its schema so it can be properly validated.

I’ll try to add the schema asap.

Thanks for reporting!

Ok. It seems that at some point they changed the schema so properties can be added back to the custom properties (see https://github.com/serverless/serverless/commit/51a10aa262af51c5df76e43a804b74c65bba010c).

I think that this whole schema validation thing is poorly documented and not very stable, so I wouldn’t rely on it.
