Hi,
I run ELK on liunx (CetnOS7) server in **intranet** environment.
Because of intranet environment, all original Map in Kibana not work.
So I want to use custom map in Kibana.
I download map geojson file form [https://exploratory.io/map](https://exploratory.io/map)
I set this in `kibana.yml`:
```
#Custom Region Maps
map.regionmap:
includeElasticMapsService: false
layers:
- name: "World Map"
url: "http://localhost:8080/world.geojson"
attribution: "https://exploratory.io/map"
fields:
- name: "WORLD"
description: "world map"
server.cors : true
server.cors.origin: "*"
```
The url is working because when I type in browser, it will download a file `world.geojson`
And set this in `elasticsearch.yml`
```
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-methods: OPTIONS, HEAD, GET, POST, PUT, DELETE
http.cors.allow-headers: X-Requested-With, X-Auth-Token, Content-Type, Content-Length, kbn-version, Origin, Content-Type, Accept, Engaged-Auth-Token
```
But when I open Maps in Kibana, it shows **blank background**.
And when I open region map in Kibana-Visualize, it also shows blank background with:
```
Error downloading vector data
Cannot download World Map file. Please ensure the CORS configuration of the server permits requests from the Kibana application on this host
```
How could I fix it?
Thank you!

It looks like you may have specified the fields incorrectly in your `kibana.yml`. There is no `WORLD` attribute in the [exploratory.io](http://exploratory.io) World Map GeoJSON file. The `fields` definition refers to the attributes in the GeoJSON file.

Hi nickpeohl,
I found official documents about:
> `fields:`
> Mandatory. Each layer can contain multiple fields to indicate what properties from the geojson features you wish to expose. The example above shows how to define multiple properties.
>
> `fields.name:`
> Mandatory. This value is used to do an inner-join between the document stored in Elasticsearch and the geojson file. e.g. if the field in the geojson is called `Location` and has city names, there must be a field in Elasticsearch that holds the same values that Kibana can then use to lookup for the geoshape data.
>
> `fields.description:`
> Mandatory. The human readable text that is shown under the Options tab when building the Region Map visualization
In tutorial example from [Custom Region Maps in Kibana 6.0 | Elastic Blog](https://www.elastic.co/cn/blog/custom-region-maps-in-kibana-6-0)
It's setting in `kibana.yml` is:
```
# Custom Region Maps
regionmap:
layers:
- name: "Australian States"
url: "http://localhost:8000/aus_state.geojson"
attribution: "https://exploratory.io/maps"
fields:
- name: "STATE_NAME"
description: "State Name"
```
And it's `aus_state.geojson` file has fields like this:
```
"properties": {
"STATE_CODE": "1",
"STATE_NAME": "New South Wales",
"rmapshaperid": 0
},
"id": 0
```
So I change my setting in `kibana.yml`:
```
#Custom Region Maps
map.regionmap:
includeElasticMapsService: false
layers:
- name: "World Map"
url: "http://localhost:8080/world.geojson"
attribution: "https://exploratory.io/map"
fields:
- name: "NAME"
description: "country name"
```
Where my `world.geojson` file has fields like this
```
"properties": {
"NAME": "Afghanistan",
"NAME_LONG": "Afghanistan",
"ADM0_A3": "AFG",
"ISO_A2": "AF",
"ISO_A3": "AFG",
"WB_A2": "AF",
"WB_A3": "AFG"
},
"id": 1
```
But it still shows same **CORS** error message.
Where is the problem?
Thank you!

What are you using to host the local GeoJSON file?
In the [blog post](https://www.elastic.co/cn/blog/custom-region-maps-in-kibana-6-0) we give an example of using `http-server --cors='*' -p 8000`. But I've found that `http-server --cors="kbn-version" -p 8000` works better.

Hi nickpeihl,
Because of intranet environment, It' unable to install http-server by using `npm install http-server -g` like what they do in [tutorial](https://www.npmjs.com/package/http-server).
And I can't find any other way to install http-server, so I use **Wildfly** to host the local GeoJSON file.

At a minimum you should make sure CORS is enabled in your Wildfly server and that it accepts the `kbn-version` header. Unfortunately, I'm not familiar with Wildfly so I do not know how this CORS is configured.

Hi nickpeihl,
Thanks for your advice about `make sure CORS is enabled` and `accepts the kbn-version header`.
I will study for it.
Thank You!!! 😀
Daniel.
