Warning: Level Streaming Doesn't Inherit From 'Actor'

What I want to do is to call an interface function from each children of MeshCreatorsInterface. But it gives this warning:

‘Level Streaming’ does not inherit from ‘Actor’. GetSectionData using MeshCreatorsInterface would always fail.

What should I do to avoid this warning?

Bump I also have this issue.

I started to get this issue after collapsing a graph. Any help would be greatly appreciated.

It’s the reroute nodes. If you don’t use them you won’t get this warning.
