Bulk Export Module geojson returning empty

I have installed Bulk Export and it’s working fine for most formats via the API but I can’t seem to get anything other than an empty FeatureCollection for geojson either for a single item or “items”.

“type”: “FeatureCollection”,
“features”: []

I suspect this is user error on my part and that the module is looking for a specific metadata field with spatial data in there but I have tried adding an item with dcterms:spatial as geographic coordinates or with a label/geonames url but that doesn’t seem to matter. I think I’m missing something pretty basic here and I’ve tried looking through the code but can’t tell exactly what I’m missing. Any help would be appreciated!
