Elasticsearch pod fails with `panic: runtime error: slice bounds out of range`

[SachinHg]

Hi,

I was using your helm repo for a PoC on EFK. When I try to deploy it on a local k8s cluster i.e, on docker-for-desktop on MacOS, I get an error on the elasticsearch operator pod. Any idea regarding this error? Help is much appreciated.

The log reads as below before terminating.

Solved the issue. I had another rogue elasticsearch operator running and it was creating issues.
