Has anyone seen this Error when using the default paper 2d template?

Development Programming & Scripting Blueprint

Hi guys,

I haven’t changed anything in the blueprint.

But the error is as followed.
Blueprint Runtime Error: “Accessed None trying to read property CallFunc_GetController_ReturnValue”. Blueprint: 2DSideScrollerCharacter Function: Execute Ubergraph 2DSide Scroller Character Graph: EventGraph Node: Set Control Rotation

The only thing I have changed in the scene is that I’ve added my own platform sprites. The character BP is untouched.

It was working, but randomly stopped. I have no idea what I did to cause this.

are you using the 4.22 version of the template?
try creating a new project with the template and see if it works

Thank you for your response! I actually found what the problem was. I will post the answer in a sec

I found the solution. The problem was that somehow the “Play” mode changed into “Simulate”, thus causing the error.
Changing it back to “Selected Viewport” fixed it.
