Абонентские и рабочие лямбда-функции Python

Question

У меня есть две лямбда-функции, написанные на Python.

1- subscriber.py (подключится к AWS MQ, соберет и отобразит сообщение)

import time
import boto3
import stomp
import json
global message

lambda_client = boto3.client('lambda')

class Listener(stomp.ConnectionListener):
    def on_error(self, headers, message):
        print('received an error "%s"' % message)

    def on_message(self, headers, message):
        print('received a message in subscriber : "%s"' % message)
        invoke_response = lambda_client.invoke(FunctionName="op_worker",
                                           InvocationType='Event',
                                           Payload=json.dumps(message)
                                           )
        #print('invoke_response a message in subscriber : "%s"' % invoke_response)
        print("terstesfsff")
        print (invoke_response['Payload'].read())
def lambda_handler(event, context):
    conn = stomp.Connection(host_and_ports=[('b-fa99d7c5-4714-4441-8166-47aae158281a-1.mq.eu-central-1.amazonaws.com', 61614)])
    lst = Listener()
    conn.set_listener('Listener', lst)
    conn.set_ssl(for_hosts=[('b-fa99d7c5-4714-4441-8166-47aae158281a-1.mq.eu-central-1.amazonaws.com', 61614)])
    conn.start()
    print('CONNECTION Started')
    conn.connect(login='test_mq', passcode='test_secure_mq',wait=True)
    print('CONNECTION established')
    conn.subscribe(destination='/queue/OnePurchasing', id=1, ack='auto')
    print('CONNECTION Subscribed')
    time.sleep(10)
    conn.disconnect()
    return

2- worker.py (который должен собрать сообщение из функции subscriber.py и передать это сообщение в Kinesis)

import time
import boto3
import stomp
import json

lambda_client = boto3.client('lambda')
kinesis_client = boto3.client('kinesis')

def lambda_handler(event, context):

    #print (invoke_response['Payload'].read())
    print('received a message in worker : "%s"' % message)
    kinesis_client.put_record(
            StreamName='OnePurchasing',
            Data=b'bytes',
            PartitionKey='1'
        )
