Malformed Lambda proxy response from AWS API Gateway calling a Lambda

Question

In my project i create a py function for check and modify my google calendar like this:

def main(event, context):      ck_app = check(event['calID'], event['datada'], event['dataa'])      if not ck_app: insert(event['calID'], event['datada'], event['dataa'], event['email'])      return {         "isBase64Encoded": False,         "statusCode": '200',         "headers": {},         "body": {'input': event,                  'busy': ck_app,                  'guest_email': event['email']}        } 

when i test it on my lambda all done, but whe i create an API from lambda:

and test it the result is:

Wed Dec 20 13:35:58 UTC 2017 : Execution failed due to configuration error: Malformed Lambda proxy response Wed Dec 20 13:35:58 UTC 2017 : Method completed with status: 502

Thanks in advance

API Gateway expects a json body so you should use something like this

import json return {     'statusCode': 200,     'body': json.dumps({'input': event,                         'busy': ck_app,                         'guest_email': event['email']}) } 

Hope this helps you forward.
