I am trying to setup Logs ML anomaly detection and getting the following error

at least one index has a field event.dataset without the correct type

Here is the typings for my index, I have seen various questions about this on here, and people have said ensure its got the right type, but never clarified which type it needs to be

```auto

Most of the `{ "type": "text", "fields": { "keyword": { "type": "keyword", "ignore_above": 256 } } }` should be `{ "type": "keyword", "ingore_above": 256 }` for this to work properly, there are some exceptions (see ECS reference below). The problem being that when `event.dataset` is a `text` field it can't be used with aggregations.

Logs (and the ML jobs) expects the schema to follow ECS: [ECS Field Reference | Elastic Common Schema (ECS) Reference [1.12] | Elastic](https://www.elastic.co/guide/en/ecs/current/ecs-field-reference.html)

Thanks, I will give this a try, pretty sure it will work, but will report back. Also, thanks for the schema.

Update - This worked, Thanks again.
