AWS CloudFormation Custom Resources Not Working

Custom Resources protocol requires a response. In this, Cloud Formation waits for a HTTPs Response and if it doesn’t have the necessary response it will eventually timeout. This can be done using cfn-response Module.

For Example:

ZipFile:

import cfnresponse  
import json
  def handler(event, context):
    responseValue = int(event['ResourceProperties']['Input']) * 5
    responseData = {}
    responseData['Data'] = responseValue
    cfnresponse.send(event, context, cfnresponse.SUCCESS, responseData, "CustomResourcePhysicalID")
