cloud_monitoring list_alarms - TypeError: __init__() takes at least 4 arguments (4 given)

[ghost]

cm = pyrax.cloud_monitoring
lst_entities = cm.list_entities()
for entity in lst_entities:
    print entity.id
    lst_alarms = cm.list_alarms(entity.id)    #this call seem to have some issue
    print lst_alarms
    break

Getting below error, not sure if I am doing something wrong or there is a bug. Please help.
