Comment 8 for bug 1714405

https://bugs.launchpad.net/juju/+bug/1613839 is the bug recently addressing an issue with a float. Given that was in bundle code I'm not sure what overlap with the actions it would be here. This also seems more around the idea of upgrading a charm and changing the type of a property in an action file. Juju isn't liking the change to the type?
