Automated Rendering with Blueprint Documentation Issue

Hello all!

I have been trying to create a blueprint to automatically render a series of videos (each with different textures) as described in the documentation. However, any time I try to run just the basics described in the documentation, I get the following error in the Output Log.

LogScript: Warning: Script Msg: A null object was passed as a world context object to UEngine::GetWorldFromContextObject().

However, I have ensured that it is properly connected and that I am using the proper variable types. I have found another forum post that describes the same issue as the one I am having.

The following is my blueprint:

Any advice or alternative methods for automated rendering is welcome. Thank you for your time!
