See the sample ini for a redirector set up that causes the issue
Enable the python plugin
during generation of python code, in GetDeprecatedFieldPythonNamesImpl notice that PreviousName.OnbectName.IsNone returns true
This is causing the python integration to issue an error that the enum conflicts with some existing type.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-171342 in the post.
