UnassignedReferenceException: The variable body of Hero has not been assigned

After finishing Chapter 3, I’m getting this error: “UnassignedReferenceException: The variable body of Hero has not been assigned.
You probably need to assign the body variable of the Hero script in the inspector.”
It doesn’t seem to be affected gameplay at all, but it gets hundreds of hits every time I run the game for 1-2 minutes.
There was a similar error appearing about not having a value for “Base Anim” in the HeroAnimator inspector, but I dragged the HeroAnimator into the Base Anim field of the Hero script in the inspector, and that error went away. If I drag MyHero into the Body field, the error goes away, but it wreaks havok on the game (the character cannot turn and face left and a Box Collider error appears that mentions that it doesn’t accept negative values for scale and size).
Are there proper settings for the HeroAnimator inspector area under Hero (Script)?

@nathansimbahan Can you please help with this when you get a chance? Thank you - much appreciated! :]
