Why doesn't the beam read the character's tag?

Question

C++ / C#

RaycastHit2D knif = Physics2D.Raycast(transform.position, Vector2.up);
  if (knif.collider != null && knif.collider.CompareTag("Player"))    
  {
       Debug.Log("Test");
  }

Moreover, without this condition, a test message is displayed.

Answer 1

Well, and print out what the beam rested on - stupidly the name of the object.
