A development build says:
<‹selector›> requires the prop "‹alias›".
The parts in ‹guillemets› are filled in from your program when it happens.
In a production build
A production build does not make this check. It catches a mistake while the program is being written, and the check is removed from a production bundle along with its sentence — so this code never appears in a production error. What the mistake does there instead depends on the mistake, which is the reason to fix it when development reports it.
