[SOLVED ]Elasticsearch-py scroll-id http.client.BadStatusLine: ''

Elastic Stack Elasticsearch
1

Hello,

Name: elasticsearch
Version: 2.3.0
Location: /usr/lib/python3.4/site-packages
Requires: urllib3

When i use scan/scroll with a large result (>1M), i have this error :

GET http://localhost:9200/_search/scroll?scroll=1m [status:N/A request:2.608s]
...
http.client.BadStatusLine: ''

After my research, this bug is already fixed here

My scroll_id make 2316 chars

If i check "elasticsearch/client/init.py", i see line 681

return self.transport.perform_request('GET', '/_search/scroll',
params=params, body=body)

So, its another bug or its the same ?

Thank for help

I think is not the same bug. I test different scroll_id with same length, and sometime works, sometime not.

The Full error message

I fixed this bug.

The cause is ES_HEAD_SIZE by default to small.
