GetComponent returns null reference

Hello, I am trying to fill a wineglass. In order to fill it it must be empty, but Unity keeps throwing an exception saying null reference. I know what null reference is, but I have no idea why it is doing it here.

If I put in:

print(target)

It correctly returns the name of the object that the raycast hits.

This is the line that is throwing an error:

 if(target.GetComponent<WineGlass>().empty == true)

And this is the entire code:

 RaycastHit hit;
             
     if (Physics.Raycast(cameraTransform.position, cameraTransform.TransformDirection(Vector3.forward), out hit, 2.0f)) {
         
         GameObject target;
         
         target = hit.collider.gameObject;
                     
         switch (hit.collider.tag) {
             
         case "WineGlass":
             
             print("WAT");                
             if(GameManager.CurrentItem == GameManager.item.WineBottle){
                 if(target.GetComponent<WineGlass>().empty == true){ 
                     interfaceManager.WriteMessage("You fill the glass");
                     GameManager.FilledWineglassCount += 1;
                     target.SendMessage("FillGlass");
                 
                     if (GameManager.FilledWineglassCount == 10){
                         CompletePuzzle();
                         GameManager.PuzzleWineComplete = true;
                     }
                 }
             }
                             
             break;

And the following is the script attached to the object:

 public class WineGlass : MonoBehaviour {
     
     public bool empty;
     
     // Use this for initialization
     void Start () {
         
         empty = true;
     
     }
     
     // Update is called once per frame
     void Update () {
     
     }
     
     public void FillGlass () {
         
         empty = false;
         print("Filling glass...");
         
     }
     
     public void EmptyGlass () {
         empty = true;
         print("Emptying glass...");    
     }
 }

I am sure it is just something that I don't understand, please help

Best Regards EKN
