AWS_LAMBDA resolver example for 2.0.0-alpha.15

[erolabzait]

Can you please provide an example of a lambda resolver.

I tried this https://github.com/serverless-appsync/serverless-appsync-plugin-example but it breaks with the latest release (^2.0.0-alpha.15)

I get this errors:

Error:
Invalid AppSync Configuration:
     at appSync/resolvers: must be object
     at appSync/resolvers/0/Query.getPost: must have required property 'functions'
     at appSync/resolvers/0/Mutation.createPost: must be object
     at appSync/resolvers/0/Mutation.updatePost: must have required property 'functions'
     at appSync/resolvers/0/Mutation.updatePost/request: must be string
     at appSync/resolvers/0/Mutation.updatePost/response: must be string
     at appSync/resolvers: contains invalid resolver definitions

I'm more interested in Mutation.updatePost

Found the issue.

To use direct lambda, set kind to UNIT and don't specify request and response (only works with Lambda function data sources).

Mutation.updatePost:
  kind: UNIT # this needs to be here
  dataSource:
    type: AWS_LAMBDA
    config:
      function:
        handler: src/updatePost.handler
        iamRoleStatements:
          - Effect: 'Allow'
            Action:
              - dynamodb:UpdateItem
            Resource: !GetAtt Posts.Arn
