Just went into my game to see. I did this tomb recently so everything's open.
One would think that by entering that first room after the entrance (passing the trigger) the hole would appear without you noticing (because it's in an area yet unexplored). There is no way to enter that room, so I added a hidden door myself.
Everything was pitch-dark, even after I had added lights. Reason being walls and floor were all black. Which indicates it isn't the intention to enter that room. Another discovery, after redecorating the room: the hole was invisible, even though my sim had passed that trigger before (and I made him do it again: nothing happened).
So I broke the link and made the hole appear and my sim investigate it. This happened.
Then nothing The hole was empty. No switch, not even a treasure. So I think it's a mistake. They probably intended something there initially but forgot.
