maas-cli "Invalid consumer"

view story

http://ubuntuforums.org – I am trying to configure and add nodes to my maas system. Every time I try to use any of the maas-cli commands, i get "invalid consumer". ~$ maas-cli maas node-groups import-boot-images Invalid consumer. ~$ maas-cli maas nodes accept-all Invalid consumer. What does this error message mean, and how can I fix this? Thanks. (Hardware)
