Hello friends.

We updated our ELK from 7.\* to 8.4.2, and we used from our backups to restoring visualization, dashboards, data views (index pattern) and ...

We had problems that were fixed, except for the following :  
I have a document in Elasticsearch that **has all metadata fields (\_index, \_id, \_score, \_source)** but **I can't use \_id in my visualizations (But I could before)**

These are some screen snip of my problem description:

How can I fix this problem ?

Thanks.

This has been a breaking change in 8.0:

> **[Elasticsearch breaking changes | Elastic Installation and Upgrade Guide \[8.0\]...](https://www.elastic.co/guide/en/elastic-stack/8.0/elasticsearch-breaking-changes.html)**

> **Details**  
> Previously, it was possible to aggregate and sort on the built-in `_id` field by loading an expensive data structure called fielddata. This was deprecated in 7.6 and is now disallowed by default in 8.0.

> **Impact**  
> Aggregating and sorting on `_id` should be avoided. As an alternative, the `_id` field’s contents can be duplicated into another field with docvalues enabled (note that this does not apply to auto-generated IDs).

Can you clarify what you are trying to achieve? Which kind of information do you want to get out of the `_id`?
