Raycast not drawing where i tell it

I would really appreciate any help on this one.

I am instantiating with raycast and mousePosition. However, there is a difference between the game scene and the editor scene. In the editor scene I can see that the prefab instantiates and moves across the ray correctly, but in the actual game this ray is nowhere near where I actually click in the scene.

My code is:

void Shoot() {

     Vector3 mousePosition = playerCamera.ScreenToWorldPoint(Input.mousePosition);

     Ray myRay = new Ray(firePoint.position, mousePosition);

     RaycastHit hitInfo;

     Physics.Raycast(myRay, out hitInfo, fireDistance);     
         
     Debug.DrawRay(firePoint.position, mousePosition, Color.red);

     Instantiate(knifePrefab, firePoint.position, Quaternion.LookRotation(myRay.direction));     
     
 }

and an example of the results are below. Notice the mouse pointer on the bottom corner of the red block. The ray is no where near it.
