Hi,

When i start my Kibana container i get the following error.

`Error: [config validation of [xpack.fleet].proxy]`

kibana.yml configs are

```auto
 xpack.fleet.proxy:
  - id: aproxy
    name: aproxy
    url: http://fleetserver:1234

```

Link to the docs is for xpack.fleet.proxy (at the bottom)  
`https://www.elastic.co/guide/en/kibana/current/fleet-settings-kb.html#_preconfiguration_settings_for_advanced_use_cases`

Any guidance would be greatly appreciated.

Here is the error in full.

```auto
