from requests_aws4auth import AWS4Auth
from elasticsearch import Elasticsearch, RequestsHttpConnection
session = boto3.session.Session()
credentials = session.get_credentials()

awsauth = AWS4Auth(credentials.access_key,
                   credentials.secret_key,
                   session.region_name, 'es',
                   session_token=credentials.token)
es = Elasticsearch(
    ['https://search-xxx.us-east-1.es.amazonaws.com'],
    http_auth=awsauth,
    use_ssl=True,
    verify_certs=True,
    connection_class=RequestsHttpConnection
)


def lambda_handler(event, context):
    es.cluster.health()
    es.indices.create(index='my-index', ignore=400)
    r = [{'Name': 'Dr. Christopher DeSimone', 'Specialised and Location': 'Health'},
 {'Name': 'Dr. Tajwar Aamir (Aamir)', 'Specialised and Location': 'Health'},
 {'Name': 'Dr. Bernard M. Aaron', 'Specialised and Location': 'Health'},

    for e in enumerate(r):
