Running UDF on Vector Cube #197
Description
reported by @mbuchhorn :
- loading vector cube with
connection.vectorcube_from_paths(which usesload_uploaded_filesprocess) - run UDF on that cube
fails with
File ".../openeo_driver/ProcessGraphDeserializer.py", line 1491, in run_udf
data = data.to_legacy_save_result()
File ".../openeo_driver/datacube.py", line 366, in to_legacy_save_result
if cube.dims == (self.DIM_GEOMETRIES, "t"):
AttributeError: 'NoneType' object has no attribute 'dims'

apparently, the VITO backend now has 3 non-official processes to load geojson data from url:
read_vector->DelayedVectorget_geometries->DelayedVectorload_uploaded_files->DriverVectorCuberunning
run_udfonDriverVectorCubeis not properly supported yet, so it might be better to use one of the others for now.also related: Open-EO/openeo-processes#322 which recommends to use
load_geojsonto load geojson from URLsoxofaan commentedon May 26, 2023
hmm, I tried to set up a POC based on
read_vector/DelayedVector, but that doesn't seem to be working either:DelayedVectorstrips out all properties along the way (keeping only the geometries):run_udf: so you can not access properties from your intput datarun_udf, e.g. insave_result: so you can not access properties that were added in the UDFIssue #197 Initial support for run_udf on DriverVectorCube

I iterated on PR Open-EO/openeo-api#200 and merged that in f83d1cf which adds initial support for doing

Closing because we have UDF support on vector cubes. We need more specific issues for remaining requests if there are any.
