Custom Editor problem with FindingProperty

Hello, I was trying to create CustomEditor for my custom list but I got null reference exception when I am trying to show it. Anyway I know why it's happening but don't know is there a way to fix it.

         for(int i = 0; i < thisList.arraySize; i++)
         {
             SerializedProperty reference = thisList.GetArrayElementAtIndex(i);
             SerializedProperty spellID = reference.FindPropertyRelative("spellID");
 
             EditorGUILayout.PropertyField(spellID);
         }

So I got this loop, it's not full yet but for the test I just put one field from my custom data. I know it would have worked if I had this kind of variable: public SpellsID spellID; But I've got something like this without any "real" fields:

 public SpellsID spellID { get; }

What you have a is a property and Unity does not serialize properties. There is no way to "fix" it.

Sad to hear that cause it's only getter/setter, it doesn't do nothing fancy and it gives you the same result as variable/field. I got it working but I had to add private fields with [SerializeField] and get it sync with getters/setters. Thank you anyway.

Unity cannot assume the property does the same as a field. Shorthand getter/setter syntax is just C# syntax sugar and the serializer sees the full get/set methods instead. It cannot assume those methods don't have unintended consequences elsewhere.
