Help: Treasured In Ice

my hero only moves in a certain way and it does not reach the chest, im not sure why
also can someone explain what Vector does

# Find the treasure inside the maze.
# When you get the treasure, move to the exit.
# The exit is marked by the red cross. The level ends when you step on the mark.
# Some doors are blocked, some open when you are near them.

exitPosition = {"x": 150, "y": 120}
distanceBetweenRooms = 16
zeroShift = {"x": 10, "y": 10}

# Escape from the maze!
# Some doors are blocked, some open when you are near them.
distance = 16
move = Vector(distance, 0)
direction = Vector.add(move, hero.pos)
while True:
    while not (hero.isPathClear(hero.pos, direction)):
        move = Vector.rotate(move, Math.PI / 2)
        direction = Vector.add(move, hero.pos)
        # hero.say(direction)
    hero.moveXY(direction.x, direction.y)
    move = Vector.rotate(move, -Math.PI / 2)
    direction = Vector.add(move, hero.pos)

can someone please help me this is my code

# I stole this

    steps.pop()
    hero.moveXY(checkPoint.x, checkPoint.y)

hero.moveXY(exitPosition.x, exitPosition.y)

it says cannot read proptery “2” of undefined
