Hi there,
We have recently moved from a single node to multi node cluster and I have set up an ILM to move from hot, warm to cold.
I keep seeing data moving from cold to warm despite it being marked as complete. I'm confused why cold data is being moved to warm. When I go to the index, I see this error:
`Index lifecycle error
null_pointer_exception: Cannot invoke "org.elasticsearch.xpack.core.ilm.Step.getKey()" because the return value of "org.elasticsearch.core.Tuple.v2()" is null`
Unfortunately I can't find anything online about this. Does anyone have any advise?
Thank you.
