Hi there,

I use `logstash-output-amazone_es 2.0.1,amazon elasticsearch, kibana 5.5.2`. It works properly for long time.

But after upgrading amazon elasticsearch 6.4, I can not create index started with **logstash-** (logstash-uat-2019.04, logstash-dev-2019.05, etc). But I can create index without started with **logstash-**

Current used ELK versions: `elasticsearch 6.4.0, logstash 6.1.1, kibana 6.4.2`

I would like to know why I can not create index started with `logstash-`  
Is it related with \_template/logstash ? If so, how to fix?  
I would appreciate for any advise 🙂
