load_stac 'crs' error

[automataIA]

Utilizzando in questo codice:

import openeo_processes_dask
from openeo_processes_dask.process_implementations import *
import numpy as np

url = "https://earth-search.aws.element84.com/v1/collections/sentinel-2-l2a"
range_time = ["2022-01-01", "2022-02-01"]
bbox =  {"east": 11.40, "north": 46.52, "south": 46.46, "west": 11.25}
properties = {"eo:cloud_cover": dict(lt=100)}

cube = load_stac(url=url, 
    spatial_extent = bbox,
    temporal_extent = range_time,
    bands=["red", "nir"],
    properties=properties,
    )

It gives me this error:

    "name": "Exception",
    "message": "Unable to parse the provided spatial extent: 'dict' object has no attribute 'crs'",
    "stack": "---------------------------------------------------------------------------

During handling of the above exception, another exception occurred:

    123 if temporal_extent is not None:
    124     start_date = None

Exception: Unable to parse the provided spatial extent: 'dict' object has no attribute 'crs'"
}

If I use load_stac with openeo client local version, everything works fine.

That's because the load_stac implementation requires the parameters to be parsed first, look at the object type required for spatial_extent and temporal_extent here: https://github.com/Open-EO/openeo-processes-dask/blob/50786cc3fe7e2dbcf3882b8e6b8a0dcf6b0e3c56/openeo_processes_dask/process_implementations/cubes/load.py#L83-L89

You can find examples on how to do that in the tests, like: https://github.com/Open-EO/openeo-processes-dask/blob/50786cc3fe7e2dbcf3882b8e6b8a0dcf6b0e3c56/tests/conftest.py#L46

and https://github.com/Open-EO/openeo-processes-dask/blob/50786cc3fe7e2dbcf3882b8e6b8a0dcf6b0e3c56/tests/conftest.py#L97
