When using a custom event in a widget that uses a struct as its input, if the pin was split to show the struct’s variables an error will appear when a variable to the widget is added, removed or modified. This error message does not do anything and disappears when the widget blueprint is recompiled.
Steps to reproduce:
- Create a structure with variables in it.
- Make a User widget blueprint.
- In the graph add CustomEvent with the input being the structure.
- Split the structure pin.
- Add a new variable to the widget and see error.
