Receive `asyncio - ERROR - Unclosed client session` when starting job

[p-phung]

I followed this example code to download some GFM data. It happened on OpenEO Editor, OpenEO Lab and a local jupyter notebook (python 3.9). All returns the same error as below. I couldn't find much info about this online.

Probably one of the past jobs leaves hanging and it is not properly closed. Or something else happens? Could you advise what to do here?

@ValentinaHutter do you know more about this sample? It's probably not an issue in the python client.

[ValentinaHutter]

Sorry for the delay, I am looking into this today!

[ValentinaHutter]

We currently have some issues with the stac collection, I will let you know once these are resolved.

[p-phung]

thanks for the heads up. Yes, please let me know!

[soxofaan]

Indeed this is not an issue with https://github.com/Open-EO/openeo-python-client but more likely https://github.com/Open-EO/openeo-processes-dask or a related component.

Unfortunately it seems I can not transfer this issue to that repo, so I created new ticket https://github.com/Open-EO/openeo-processes-dask/issues/265 and I'll close this one

[ValentinaHutter]

This should now work again, but you have to change the names of the bands, see https://github.com/Open-EO/openeo-processes-dask/issues/265 will be updated in the community-examples soon. (currently it's an open PR, I don't have permission to merge it.)
