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

Action Reasoning:
The next best action is to paint the tile directly below the robot, tile_1-4, with the color black, which the robot is currently holding. This action moves us closer to the goal state by painting another tile in the required pattern.

New State Description:
- Robot1 is on tile_0-5, holding the color black.- Tile_0-5 is occupied by Robot1.- Tiles tile_1-3 and tile_1-5 are painted white and are no longer clear.- Tile tile_1-4 is painted black and is no longer clear.- Tiles tile_0-1, tile_0-2, tile_0-3, tile_0-4, tile_1-1, tile_1-2 remain clear and unpainted.- The colors white and black are available for switching.
