I am trying to do a buffer with WPS request builder of GeoServer. I copied the URL of the gml3 output in GeoServer:
and I pasted it as the input URL
I ran the process and I received the following error:
JTS:bufferBufferReturns a polygonal geometry representing the input geometry enlarged by a given distance around its exterior.Failed to retrieve value for input geom
What can I do to fix it? Is the way I gave the URL as input of the process correct?
Should I change the name of the geom column of the input data?
