Comment 4 for bug 1386470

Oh right, doing a request with a missing parameter (for e.g node-create w/o the driver) and a valid user seems to make the error apparently:

stack@virtual-machine:~/devstack$ source ~/devstack/accrc/admin/admin
stack@virtual-machine:~/devstack$ ironic node-create -i test=test
'unicode' object has no attribute 'get'
