just before digging deeper: Is there any reason using of not using the [high level rest client](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.4/java-rest-high.html)?

Are you aware of [date math support in index names](https://www.elastic.co/guide/en/elasticsearch/reference/7.4/date-math-index-names.html) and [index templates](https://www.elastic.co/guide/en/elasticsearch/reference/7.4/indices-get-template.html), that prevents you from creating any indices manually?

That sounds as if you would not need to do any index creation in your own code at all.
