Animator not initialized "cautions"

I have read the forums and it seems like adding a coroutine or yield to wait for initialization seems a monumental chore. I get 999+ caution warnings - not errors, but the yield sign warning. and no logic for any that I have explored . for instance,I have a SetTrigger call in an OnTrigger Enter. Clearly the animator should have initialized in the start or even an awake function and this can't be a matter of trying to initialize and set a trigger in the same frame.I mean I have not even asked the animator to do anything yet and unity is telling me that line of code is a "caution" because the animator has not been initialized. I have been ignoring it because it works - none of my 999+ "cautions" break the game as when I enter the trigger zone the animation.SetTrigger works so what is the deal? My builds are fine and everything works fine so why these 999+ annoyances?
