Failure to PutObject(s) Lettuce and Bread onto Fridge - no valid positions found about ai2thor HOT 2 CLOSED

Hello! The issue here is there is a built in visibility reliant check related to this action. If you do not set ForceAction=True then the object may fail to find a position if the agent is not able to see the object after the placement. This is why when you set ForceAction=True the object is successfully placed but it disappears from sight, the object is being placed in the free space further back in the fridge.

There are two ways to get around this. You can either position the agent such that it has a better sight of where it is trying to put something, so lowering the camera angle by crouching might be needed. You can also just validate an object is successfully placed via the action metadata directly, even though you won't have direct visual confirmation from the returned visual frames.

Additionally, you may be seeing different behavior across different fridges and scenes because the layouts of the scenes and the size, height, and internal dimensions (free space) of fridges are all very different from each other especially across scenes.

Yep, I did forceAction=True and the object was indeed just above the agent's eyeline. Thanks!
