Snapcraft list-revisions

Hi,

I am getting this error on snapcraft list-revisions today:

$ snapcraft list-revisions kubelet
Sorry, an error occurred in Snapcraft:
None is not of type 'string'

Failed validating 'type' in schema['properties']['revisions']['items']['properties']['base']:
    {'introduced_at': 1, 'type': 'string'}

On instance['revisions'][15]['base']:
    None

Confirmed. @sergiusens one for you…

This is a simple fix, Snap Store API seems to be incorrect and all our testing for the migration was using bases.

Fix upcoming.

Fix will be available in 4.4.2, soon to be found on edge.
