Can you provide more details on your serverless.yml or your service configuration, or can you provide a test configuration with which I can reproduce the issue?
I assume that this is a bug that is restricted to a specific resource type or trigger.

this is my serverless.yml

service: users

provider:
  name: aws
  runtime: nodejs6.10

  stage: dev
  region: us-west-2
  profile: xxxxxx


functions:
  authAdmin:
    handler: authorizer.custom
  hello:
    handler: handler.hello
    events:
      - http:
          path: hello
          method: get
          authorizer:
            arn: arn:aws:cognito-idp:us-west-2:xxxxx:userpool/us-west-xxxx
  helloAdmin:
    handler: handler.helloAdmin
    events:
      - http:
          path: admin

Many thanks for the information 🙌 . I'm sure it has something to do with the authorizer declarations. I will look into the issue soon.

thanks @HyperBrain , for custom authorizer i use this

Just isolated the issue. It is caused by:

authorizer:
  arn: arn:aws:cognito-idp:us-west-2:xxxxx:userpool/us-west-xxxx

The plugin should ignore User Pools authorizers and pass them unchanged. Working on a fix.
