Finding the index of a gameobject by name

Question

Hi, Excuse my foolishness. I'm trying to make it so that the player enters a string and if a gameobject by that name exists, we'll instantiate it. I did the following but of course it doesn't work. I wasn't able to find anything related to this (could be my fault) and I'd like to ask you guys for help.

     public string name;
     public GameObject inputField;
     public List<GameObject> objects;
 
     int object_index;
 
     public Transform player;
 
     public void Creator_Input()
     {
         name = inputField.GetComponent<Text>().text;
         Debug.Log(name);
         int indexofcreation = objects.IndexOf(name); 
         Instantiate(objects[0], new Vector3(player.position.x, player.position.y, player.position.z - 2), Quaternion.identity);
 
     }

  public Text inputField; // Drag & drop the gameObject with the Text component in the inspector
  public List<GameObject> objects;
 
  public Transform player;
 
  public void Creator_Input()
  {
      int objectIndex = objects.FindIndex(gameObject => string.Equals(inputField.text, gameObject.name));
      if(objectIndex >= 0)
          Instantiate(objects[objectIndex], new Vector3(player.position.x, player.position.y, player.position.z - 2), Quaternion.identity);
   }

It underlines the "FindIndex" and says " The type arguments for method "Array.FindIndex(T[], Predicate )" cannot be inferred from the usage. Try specifying the type of arguments explicitly.

$$anonymous$$y bad, I don't know why I used this method since objects is a List.... Code fixed

Well that fixed the error in the code but now when I try and execute the function. It says " Object reference not set to an instance of an object". I know that I keep bugging you but I really need help :p
