KeyError: "No variable named 'ag_cloud_mask'

Not sure if this is a bug, or incorrect use. I followed the approach on https://earthdaily.github.io/earthdaily-python-client/_auto_examples/first_steps_create_datacube.html (Create datacube in three steps):

Start with the linked “Create datacube in three steps” example and reproduce the KeyError for the missing `ag_cloud_mask` variable. Check the complete usage context and expected datacube variables; done means documenting whether this is incorrect usage or a reproducible client bug, with enough detail to guide a fix.
