How to fix "'AnimationEvent has no receiver! Are you missing a component?"

I use unity-chan to apply this animation “Unity Asset Store - The Best Assets for Game Making
but it raise

'unitychan' AnimationEvent 'FootL' has no receiver! Are you missing a component?

how to fix it?

The solution is, for ex

'unitychan' AnimationEvent 'FootL' has no receiver! Are you missing a component?

it means unitychan’s some animation will invoke “FootL” in unitychan script
it means, I should add public SomeType FootL() in unitychan object script component
