What I'm doing here wrong?

[essocholik 0]

mp.events.addCommand("sethp", (player) => {
    player.setHealth(150);
});

and there's error in debug:

TypeError: player.setHealth is not a function
player.setHealth(150);

i just wanted to set player who used command health to 50%

you have to use player.health = 150 instead of setHealth, and my guess is that you have to set lower than 100.
