"FeatureType Grid Widget" returns empty geometries when a spatial filter is set

afabiani commented 2 years ago

Expected Behavior

When trying to download a dataset with a spatial filter applied like shown her below, I'd expect the process correctly generating the output file

Actual Behavior

The Download Process fails with an Empty Geometries Null Pointer Exception error

Steps to Reproduce the Problem

Open the grid editor widget on a vectorial dataset
Create a map filter
Try to download the filtered data

after some investigation, the problem seems to be on the geoserver side

this is the request done to geoserver:

mapstore send wps:Data, unless the ogc filter is not valid for geoserver, the problem seems to be on that side

Notice that when the same polygon is set a ROI input to the WPS process, everything works fine. Attributes filters are also working fine.
