Error message when calling Animator.Play(): Invalid Layer -1 ?

I am trying to do a simple animation with a simple state machine, but Unity prints out an error message:

Invalid Layer Index '-1' UnityEngine.Animator:Play(String, Int32, Single)

I have printed out all the layer IDs and they are all "-1", which should work. But, unfortunately, Unity keeps prints out the same error above.

I am using the latest version of Unity 5.5.2

Here is the code:

using UnityEngine;

public class Thanh_Space_Man : MonoBehaviour {

 public Animator anim;

 // Use this for initialization
 void Start () 
 {
     anim = GetComponent<Animator> ();   
 }

 // Update is called once per frame
 void Update () 
 {   

     if(Input.GetKeyDown("1"))
     {           
         anim.Play ("Run_Rifle_Forward", -1, 0f);            
     }

     if(Input.GetKeyDown("2"))
     {
         anim.Play ("Idle_Rifle_01", -1, 0f);
     }


 }

}
