filter_temporal/filter_spatial usage gives weird error

[soxofaan]

I was playing around with cross-backend workflow execution and stumbled on this problem in the EODC backend:

import openeo
connection = openeo.connect(url="openeo.eodc.eu").authenticate_oidc()

temporal_extent = ["2020-08-01", "2020-08-10"]
bbox = {"west": 5.07, "south": 51.21, "east": 5.10, "north": 51.23}

cube = connection.load_collection(
    "boa_sentinel_2",
    bands=["B03"],
)
cube = cube.filter_temporal(temporal_extent)
cube = cube.filter_bbox(bbox)
result = cube.save_result(format="NetCDF")

result.download("tmp.nc")

The download fails with

OpenEoApiError: [500] Internal Error: 'NoneType' object is not subscriptable

Note that doing the temporal/spatial filtering directly in load_collection (instead of filter_temporal/filter_spatial) works, e.g.

cube = connection.load_collection(
    "boa_sentinel_2",
    temporal_extent=temporal_extent,
    spatial_extent=bbox,
    bands=["B03"],
)

If I run it as a batch job, I get these batch job logs:
