Hey guys! I create a file with some authentication functions to run at Api Gateway :slight_smile: Locally I can invoke the functions point to my redis local and all works fine, when I run it on productions I get this stack on Cloud Watch:

Unable to import module 'handler': Error

My serverless.yml

service: gandalf
provider:
  name: aws
  runtime: nodejs8.10
  stage: production
  memorySize: 256
functions:
  createSession:
    handler: handler.create
    events:
      - http:
          path: /session
          method: post
  removeSession:
    handler: handler.remove
    events:
      - http:
          path: /session
          method: delete
  verifySession:
    handler: handler.verify
    events:
      - http:
          path: /session
          method: get
  refreshSession:
    handler: handler.refresh
    events:
      - http:
          path: /session
          method: put

All dependencies that I used was in my package.json

  "dependencies": {
    "jsonwebtoken": "^8.3.0",
    "redis": "^2.8.0",
    "serverless": "^1.30.1"
  }
