Остановите базу данных AWS Аврора с помощью лямбда-функции с помощью Python 2.7

Я использовал следующую лямбда-функцию, чтобы остановить мою базу данных rds aurora.Но это всегда заканчивается ошибкой «Объект RDS не имеет атрибута 'stop_db_cluster' ».Может ли кто-нибудь помочь мне здесь; 

import sys
import botocore
import boto3
from botocore.exceptions import ClientError
def lambda_handler(event, context):
    client = boto3.client('rds')
    lambdaFunc = boto3.client('lambda')
    print ('Trying to get Environment variable')
    try:
        funcResponse = lambdaFunc.get_function_configuration(
            FunctionName='RDSInstanceStop'
        )
        DBinstance = funcResponse['Environment']['Variables']['DBInstanceName']
        print ('Stoping RDS service for DBInstance : ' + DBinstance)
    except ClientError as e:
        print(e)    
    try:
        response = client.stop_db_cluster(
            DBClusterIdentifier='DBInstanceName'
        )
        print ('Success :: ' )
        return response
    except ClientError as e:
        print(e)    
    return
    {
        'message' : "Script execution completed. See Cloudwatch logs for complete output"
    }

Мне пришлось переписать лямбда-функцию с помощью Runtime Python 3.7: 

import botocore
import boto3

rdsId = 'data-cluster-d9xka2hfg766'

def stopRDS():
    rds = boto3.client('rds')
    instances = rds.describe_db_clusters( DBClusterIdentifier=rdsId)

    status = instances.get('DBClusters')[0].get('Status')

    if status == 'available':    
        resp = rds.stop_db_cluster(DBClusterIdentifier=rdsId)
        print('Requested to stop rds: ' + str(rdsId))  
    else:
        print('RDS ' + str(rdsId) + ' is ' + str(status))

def lambda_handler(event, context):
    stopRDS()
    return 'Stopped environment.'

Это известная проблема

С https://github.com/boto/boto3/issues/1723

Похоже, что эти операции были недавно добавлены, и во время выполнения лямбды может отсутствовать последняя версия boto3, что означает операциюне доступноВам нужно будет связать более новую версию SDK с вашим лямбда-пакетом.Вот несколько документов по этому поводу: https://docs.aws.amazon.com/lambda/latest/dg/lambda-python-how-to-create-deployment-package.html
