Log spammed with Unknown Function

Development Programming & Scripting Blueprint

I’m working in Lyra designing my own widgets. The widget I’m working on is derived from LyraActivatableWidget. All of a sudden, when I compile the widget the output log is being spammed with the following.
LogClass: Warning: Short type name “None” provided for TryFindType. Please convert it to a path name (suggested: “None”). Callstack:

ULyraEditorEngine::Tick() [G:\trunk\Altair_Dev\Source\LyraEditor\LyraEditorEngine.cpp:50]

Why is this happening. If I look at LyraEditorEngine.cpp its calling FirstTickSetup().
I can’t make these lines go away. Has anyone any ideas? This is running the Lyra 5.1 project.

This is one of the most misleading things i’ve ever encountered in UE development. The cause of this was a blueprint had somehow lost its c++ parent, so it was showing in the editor as having no parent. I deleted the Intermediate folder, regenerated the c++ project and rebuilt, and now the errors have gone away, and the blueprint in question is derived from the right c++ class.

Had the same with data structures. Recompiling of the blueprint where these data tables were used - fixed the issue
