'Dataset' object has no attribute 'openeo'

When building a process graph on a ZARR local datacube, an openeo attribute/accessor on the DataCube object is accessed but not found when calling the execute() on the graph.

[!] load + chain process

zarr_oed = local_conn.load_collection(zarr_path.as_posix())
zarr_oed_filter = zarr_oed.filter_bbox(west=11.00, east=11.50, north=46.80, south=46.40)
zarr_oed_filter.execute()
"'Dataset' object has no attribute 'openeo'"

NOTE, also tried with:

• zarr_oed_filter = zarr_oed.filter_temporal("1970-01-01T12:00:00Z", "1980-01-01T00:00:00Z")

Relevant environment:

• openeo 0.42.1
