Hello Guys,
I'm facing trouble to implement a map that reads data from an index with documents like:
```
{
"name": "Uncle Bob Farm",
"geo":[
{
"area": 10,
"geoJson": {
"type": "MultiPolygon",
"coordinates": [
[
[
[
-48.94664341287877,
-26.659539686978484
],
[
-48.946374692073086,
-26.65953713216144
],
...
```
Well, I tried to search the index, and run vega flatten transform... It did not work.
Is there any way to debug the vega execution?
Thank you

@nyuriks could you help out here, please. You know the debug possibilities the best.

Thank you @timroes. Actually I found the specific information on kibana docs. Thank you again.

@diogopontual does your document contain multiple geojson objects (geo is a list of objects)? While i think this is a bit strange because geojson itself could contain multiple features with properties, you could use flatten on the geo field to create individual entries. Geojson can then be used directly by [geopath transformation](https://vega.github.io/vega/docs/transforms/geopath/).
To debug, see [https://www.elastic.co/guide/en/kibana/6.x/vega-debugging.html](https://www.elastic.co/guide/en/kibana/6.x/vega-debugging.html) for in-depth details. You can view what your data looks like in the browser's debugger. Hope this helps.
