console window i got this pls tell me how to solve this.
Unfortunately this did not work for me, but i found an other solution.
In your project, select the model (in my case an .fbx)
Then, in the Rig tab, set animation type to Legacy. Done 
Solved on this post!

So old post but it comes to top when search the warning. So I came to answer.
Answer is you have Animation Component and its useless in your gameobject. Remove it and you are wont get this message again. Probably you were using Animators to animate sprites.
But you dont need animation component in your gameobject.
