There is a another problem confuse me even more 😅 After saving a ziva rig file, I can load it back in the scene even though the script editor show error above, but ziva function seem working fine. Then I next time re-enter Maya, in the same scene, using save ziva rig file load ziva rig, script editor show a Error: u'zBuilder.parameters' and the load function failed... 🙁
