elasticsearch exception SerializationError - python-2.7

Question

From python script i am sending data to elasticsearch server
this will help me to connect to ES
es = Elasticsearch('localhost:9200',use_ssl=False,verify_certs=True)
and by using the bellow code i am able to send all data to my local ES server
es.index(index='alertnagios', doc_type='nagios', body=jsonvalue)
But when i am trying to send data to cloud ES server,the script is executing fine and it is indexing few documents after indexing few documents i am getting following error
Traceback (most recent call last):
File "scriptfile.py", line 78, in <module>
es.index(index='test', doc_type='test123', body=jsonvalue)

raise SerializationError(s, e)
elasticsearch.exceptions.SerializationError: (u'order=0></iframe>', JSONDecodeError('No JSON object could be decoded: line 1 column 0 (char 0)',))
The same script is working fine when i am sending data to my localhost ES server , I don't know why it is not working when i am sending data to cloud instance
Please help me

The problem is resolved by using Bulk indexing method ,when we are indexing to local server it won't be a matter if we index documents one after the other ,but while indexing to cloud instance we have to follow bulk indexing method to overcome from memory issues and connection issues
if we follow bulk indexing method it will index all the documnets once into a elasticsearch and no need to open connection again and again,it won't take much time.
here is my code
from elasticsearch import Elasticsearch, helpers
jsonobject= {
'_index': 'index',
'_type': 'index123',
'_source':jsonData
}
actions = [jsonobject]
helpers.bulk(es, actions, chunk_size=1000, request_timeout=200)
