class 'NoneType' after vector_to_raster

[VincentVerelst]

After converting a VectorCube to a RasterCube using the vector_to_raster process, I get a ProcessParameterInvalidException when applying a process. The following code snippet is an example, when trying to apply the rename_labels process to the result of vector_to_raster:

...

scl = c.load_collection(
    "SENTINEL2_L2A",
    spatial_extent=spatial_extent,
    temporal_extent=temporal_extent,
    bands=["SCL"],
)

classification = scl.band("SCL")
binary = (classification == 3) | (classification == 8) | (classification == 9) | (classification == 10)

cloud_coverage = (1 - binary).aggregate_spatial(geometries=aoi_polygon, reducer='mean')
cloud_coverage_raster = cloud_coverage.vector_to_raster(scl)
cloud_coverage_raster = cloud_coverage_raster.rename_labels('bands', ['score'])

cloud_coverage_raster.execute_batch()

This results in: ProcessParameterInvalidException(status_code=400, code='ProcessParameterInvalid', message="The value passed for parameter 'data' in process 'rename_labels' is invalid: Invalid data type <class 'NoneType'> expected raster-cube.", id='no-request').

This problem is not specific for rename_labels as I've been able to reproduce it with other processes as well.

When running the above code on the CDSE staging backend, there is still a very similar error message:

ProcessParameterInvalidException(status_code=400, code='ProcessParameterInvalid', message="The value passed for parameter 'data' in process 'rename_labels' is invalid: Invalid data type <class 'openeo_driver.save_result.AggregatePolygonResult'> expected raster-cube.", id='no-request')

The AggregatePolygonResult as return type is a separate issue: #276
The issue described here is fixed.
