Which version of the plugin do you use? The 3.4.x version?

this one: https://github.com/neo4j-contrib/neo4j-elasticsearch/releases/tag/3.4.5

Also seeing this issue. Using plugin 3.4.5, against multiple version of ES, from 6.1.2 to 6.4.5. Running inside docker. It seemed to go away after switching up to Neo 3.4.9

Thanks for reporting that.
