Error while running workflow

[vfxfisher]

I am using the UI_Divider and when I execute a workflow I get an error stating:

Required input slots have no connection feeding them.

UI Divider is missing a required input: divider

---

This does NOT prevent the workflow from completing; however, it is rather unsightly.

Odd -

I do not know what happened; but the error appears to have disappeared and is not longer being thrown during execution
