We have an index in the format "app-service-log". There are no aliases defined on the index. When I try to create another index with the name "app-service-log1" it is throwing an invalid alias name exception
> Invalid alias name [app-service-log], an index exists with the same name as the alias
Any idea what may be the issue here or i need to check some where else.

I think this indicates that Elasticsearch is trying to create the index `app-service-log1` with an alias called `app-service-log`, which isn't working because there's already an index called `app-service-log`. The aliases used when creating an index come from (a) the index creation request itself and (b) the [index templates](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-templates.html). Could you check these two places to see where this alias is coming from?
