The Basic Rules state: "If the target isn’t in the location you targeted, you automatically miss, but the DM typically just says that the attack missed, not whether you guessed the target’s location correctly."
Based on the surrounding context in this section, I think it's inferred here that the player made an attack roll, even though his or her character had no chance of hitting. But that becomes an issue if the player has rolled high enough that it would almost certainly have been a hit against any creature (especially if a critical hit). The player can figure it out fairly easily that the monster was not in the spot that was targeted. So I think it's best to just skip the charade and call for no attack roll once the player has committed to the action, and just let him or her know the creature wasn't in the spot that was targeted. The player has just "wasted" an attack. I think a decent consolation prize is knowing with certainty that the monster isn't in that spot. I don't see that there's much to be gained by being coy about it.
