Ошибка в Quaternion.Lerp

Выскакивает ошибка, никак не могу исправить. На работу вроде не влияет, но их много очень вылетает. (Assertion failed: Assertion failed on expression: '!CompareApproximately(aScalar, 0.0F)' UnityEngine.Quaternion:Lerp(Quaternion, Quaternion, Single) Swipe:FixedUpdate() (at Assets/scripts/Swipe.cs:36) )

public class Swipe : MonoBehaviour, IDragHandler {
    Vector2 delta;
    Quaternion originRotation;
    Quaternion rotateY;
    Quaternion rotateX;
    GameObject Camera;
    Quaternion targetRot;
    private void Start()
    {
        Camera = GameObject.FindGameObjectWithTag("MainCamera");
    }
    public void OnDrag(PointerEventData eventData)
    {
        delta = eventData.delta;
        delta.x = Mathf.Clamp(delta.x, -2f, 2f);
        delta.y = Mathf.Clamp(delta.y, -2f, 2f);
        originRotation = Camera.transform.rotation;
        rotateY = Quaternion.AngleAxis(-delta.y, Vector3.right);
        rotateX = Quaternion.AngleAxis(delta.x, Vector3.up);
    }
    private void FixedUpdate() 
    {
          targetRot = originRotation * Quaternion.Euler(-delta.y, delta.x, 0f) ;
          Camera.transform.rotation = Quaternion.Lerp(transform.rotation, targetRot, 1);
          Camera.transform.rotation = Quaternion.Euler(Camera.transform.rotation.eulerAngles.x, Camera.transform.rotation.eulerAngles.y, 0.0f);

    }
