This was the code which was pack with virtual env & request etc was uploaded to s3 & shows up ok

Most possible reason of permission or VPC i think is not case here ..

Below is also correct : handler : slackAlert.send_slack

Any suggestions please

import boto3
import json
import requests

webhook_url = "https://hooks.slack.com/services/T03AWS5EYLU/xxxx/xxxx"


def send_slack(event, context):
  print(str(evebt))
  slack_message = {'text': 'EC2 Stopped'}
  response = requests.post(webhook_url, data=json.dumps(slack_message))
  return response.text
