Pawn is not valid?

I’m very new to UE4 and was following the youtube tutorial on animation blueprints. The tutorial said to check if the character is valid, and my character is not, even when I simulate.

If you hit simulate you are simulating your level, but no characters is spawned or no player controller is created for you, this happens when you hit play. Simulating is useful for fast iteration on level building.

I am hitting play, I just used the wrong terminology.
