Issues with lambdaAuthorizer

[Magnus1987]

We try to use the example code provided with the documentation. Swagger page gets generated but using lambdaAuthorizer we only end up with "Event references not configured authorizer". We reference an existing lambda authorizer in our code below:

custom:
  customAuthorizer:
    name: sws-lambda-authorizer-dev-authorize
  autoswagger:
    title: 'AutoSwagger Page'
    lambdaAuthorizer: ${self:custom.customAuthorizer}

functions:
  - hello-world-api:
      handler: src/hello-world-api.handler
      timeout: 30
      events:
        - http:
            path: api/hello
            method: GET
            authorizer:
              arn: arn:aws:lambda:eu-west-1:${env:account}:function:sws-lambda-authorizer-${env:STAGE}-authorize:stable
              identitySource: method.request.header.Authorization
