Problem with mask in OpenEO local python library

[automataIA]

I wanted to load a cube, using the example at link, and process it locally (the classic method for cloud removal via SCL band). the code I used to create the cube is:

from openeo.local import LocalConnection
import matplotlib.pyplot as plt  
import xarray   
import numpy as np
import pprint

url = "https://earth-search.aws.element84.com/v1/collections/sentinel-2-l2a"
spatial_extent = {"west": west, "south": south, "east": east, "north": north}

temporal_extent = ["2022-01-01", "2022-02-01"]

bands = ["red","green","blue", "scl"]

properties = {"eo:cloud_cover": dict(lt=100)}

s2_cube = local_conn.load_stac(
    url=url,
    spatial_extent=spatial_extent,
    temporal_extent=temporal_extent,
    bands=bands,
    properties=properties,
) 

s2_cube.execute()

And it doesn't give me any errors. Instead, when I go to do the various necessary processes:

scl_band = s2_cube.band("scl")

cloud_mask = (scl_band == 3) | (scl_band == 7) | (scl_band == 8) | (scl_band == 9) | (scl_band == 10) 

cloud_mask = cloud_mask.resample_cube_spatial(s2_cube)

cube_masked = s2_cube.mask(cloud_mask)

composite_masked = cube_masked.min_time()

composite_masked.execute()

It gives me this error:

Unexpected exception formatting exception. Falling back to standard exception

Is this a library error? How can I solve this problem to be able to do the various processes locally? Win 11, wsl2, vscode, ubuntu, pyenv.

This is a problem in the openeo-processes-dask library. The mask process was only added recently there: https://github.com/Open-EO/openeo-processes-dask/pull/165

what version of the openeo-processes-dask library is currently installed in your environment?

If I understand correctly, mask was added in version 2024.1.1

Ok. Now I have a meta-question. I'm trying to build an openeo back-end(python based) which uses a stac catalog address (example: https://earth-search.aws.element84.com/v1/collections/sentinel-2-l2a).

Where(link, forum, community) can I ask these questions and other relevant questions for this topic?

The openeo python client repo is indeed not the ideal place to discuss that.

The best option currently I think is the openEO Platform forum at https://discuss.eodc.eu/c/openeo-platform/5

Assuming the original problem is solved, I'm going to close this. Feel free to reopen
