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
