Animator is not playing an AnimatorController on action that change face direction to character

Excadrix

I'm not sure when exactly this problem appeared because I've done 2-3 updates of AC from the last time I tested it.
Right now I have Unity 2017.2.0f3 and AC 1.62.6
Animation Engine : Sprites Unity and motion control Automatic
When I use the action  Character -> Animate  Reset to idle or Character Face Direction I get the AC warning.
"Animator is not playing an AnimatorController."
Any idea how to fix it? What information more do you need to upload?
Thank you.

The error suggests that the character's Animator component has no Controller assigned - is this the case?

Let's see the Action itself, as well as the state of the Animator component at the time the error shows.  Are you assigning a character, or just checking "Is Player"?  If you're assigning a character, are you assigning a prefab, or an object in your scene?

I fixed it by creating the player again with the wizard and assigning the same values etc etc...
Before I do that though I tried to fix it with other ways.

Checked the  Affect Player checkbox first.. Then tried to assign a prefab and  then an object still the same error.
I checked Settings and the  character was assigned normally
Also I putted a debug log
Debug.Log(GetComponent<Player>().GetSpriteDirection());
to check the direction which showed the correct one.
Walk animation worked fine too.

Anyway it is one of those bugs that you never found out why they happened
