Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
Since the robot is on tile_1-3 and holding black, and the tile directly below (tile_2-3) is already painted black, we should move right to position the robot above a clear tile (tile_1-4) to prepare for painting.
