Direction of paremeter doesn't match?

Development Programming & Scripting Blueprint

I don’t even understand what this error is.

Static Mesh Component -> Get Overlap Infos -> Length -> Set Integer Variable

The Get Overlap Infos node errors out with the following error: Error The direction of Return Value doesn’t match the direction of parameter ReturnValue

I have exactly the same problem. A bug in the function? Or maybe it’s not supported in Construction Script?
