errorMessage": "Unable to import module 'handler'

Serverless Framework
1

I am trying to get started with the serverless framework. I followed the AWS quick start guide and instead of Nodejs, i am using python. However, am getting the following error while trying to invoke the function.

{
    "errorMessage": "Unable to import module 'handler'"
}

But, If I manually edit the function from the lambda editor and invoke it, it is not throwing any error. It is throwing an error only when invoking through the serverless framework.

Have you defined the right runtime for your service? It sounds like the service is trying to import your Python code as a Node module…

also getting these all of sudden today, checked everything, deleted node_modules etc etc etc .

Any ideas how to resolve this?
When running sls deploy -v the function gets created in Lambda with the expected environment variables. When I execute the Lambda function I get:

{
  "errorMessage": "Unable to import module 'handler'"
}

Here’s my code:
handler.py

import os


def hello(event, context):
    FN = os.environ('FIRST_NAME')
    print('First Name: ', FN)

serverless.yml

service: python-env-vars-ex

provider:
  name: aws
  runtime: python3.6
  profile: serverless-admin
  region: ap-southeast-2
  environment:
    var1: "val1"
    var2: "val2"
    FIRST_NAME: "Ultradox"

functions:
  hello:
    handler: handler.hello
