Description

From 18 April 2017 AWS Lambda has python3.6 https://aws.amazon.com/releasenotes/5198208415517126

• What went wrong?
  I configured runtime: python3.6 in serverless.yml
  sls invoke local -f hello errored

• What did you expect should have happened?
  sls deploy followed by sls invoke -f hello was successful

  stage: dev
  region: eu-west-1

functions:
  hello:
    handler: handler.hello
    events:

handler.py

import json

def hello(event, context):
    response = {
        'version': '1.0',
        'response': {
            'outputSpeech': {
                'type': 'PlainText',
                'text': 'Go Serverless v1.0! Your function executed successfully!',
            }
        }
    }
