How to get Rookie Mistake

Game data

In-game condition: “Attempt to use a Ferrofluid Flask with none remaining.”

Rookie Mistake unlocks when you try to drink a Ferrofluid Flask with none left. Use up every Flask, then press the heal button once more: the game counts the failed attempt.

Do it somewhere safe, next to a Lantern, so you can rest straight afterwards. If you are below 20% Health at that moment, interacting with the Lantern also unlocks In the Nick of Time, so the two are easiest together.
