Inside Puzzle.java, Puzzle constructor should surround with "try and catch" to prevent the error shown.

Modification of code:

public Puzzle(String path) {
		JSONObject jsonObj = null;
		
		try {
			Path file = Path.of(path);
			String obj = Files.readString(file);
			jsonObj = new JSONObject(obj);

			// store the JSON obj, for other classes to access
			this.puzzleJSON = jsonObj;

			name = (String)jsonObj.get("PuzzleName");
			description = (String) jsonObj.get("Description");
			roleList = jsonArray2arrayList((JSONArray) jsonObj.get("Roles"));

			JSONArray jsonArray;
			jsonArray = (JSONArray) jsonObj.get("InitialState");
			initialState = new PuzzleState(jsonArray2arrayList((JSONArray) jsonArray.get(0)),
					jsonArray2arrayList((JSONArray) jsonArray.get(1)), 0);
			jsonArray = (JSONArray) jsonObj.get("TargetState");
			targetState = new PuzzleState(jsonArray2arrayList((JSONArray) jsonArray.get(0)),
					jsonArray2arrayList((JSONArray) jsonArray.get(1)), 0);

			travelables = new HashSet<String>(jsonArray2arrayList((JSONArray) jsonObj.get("Travelable")));
		} catch (Exception e) {
			System.out.println(e.getMessage());
	}
	
		
	}
