[Koha] Elasticsearch in Koha 18.11

[cfhong]

Hello,

Have anyone using Elasticsearch feature in Koha 18.11? I was following steps
in

https://wiki.koha-community.org/wiki/Commands_provided_by_the_Debian_packages#koha-elasticsearch

and 

https://wiki.koha-community.org/wiki/Elasticsearch/Implementation

I got this error on the log when I run
misc/search_tools/rebuild_elastic_search.pl.

Indexing biblios
[Request] ** [http://127.0.0.1:9200]-[400] [illegal_argument_exception]

Please advise.
