import json

session = boto3.session.Session()
print(session)
credentials = session.get_credentials().get_frozen_credentials()
print(credentials)
es_host = 'https://search-myelasticsearch-url:443'
awsauth = AWSRequestsAuth(
aws_access_key=credentials.access_key,
aws_secret_access_key=credentials.secret_key,
aws_host=es_host,
aws_region='us-east-1',
aws_service='es')

def getdata(event, context):
