Hi,

In the index template, I forgot to define the index.lifecycle.rollover\_alias and triggered the following error:

> Index lifecycle error
> 
> illegal\_argument\_exception: setting [index.lifecycle.rollover\_alias] for index [xxxxx-index] is empty or not defined

I just updated the index template with providing the rollover\_alias.

I would like to ask how to fix the created index with the missing "rollover\_alias".

Thanks.
