How to make variables work in a command?

Question

In contact with

I use the NodeJS module vk-io vkcoin api

I made a command to get a repost bonus, but the variables do not work in it, that is,
they give 30k for a subscription and they are not credited to the user's balance

cmd.hear(/^(?:Бонус)$/i, async (message, bot) => {
return message.send("[] ~ Ты получил бонус за подписку в размере 30.000 vkc")
let user = message.user;
message.user.zapas.z3 += 2
message.user.balance += 30000

vk.api.groups.isMember({ 
group_id: 194310586, 
user_id: message.user.id }).then((response) => {
if(message.user.zapas.z3 > 1) return message.send(` ~ Ты уже получал бонус за подписку`);
if(response == 0) return message.send(`[] ~ Для получения бонус ты должен быть подписан`);

});
});

Good evening, make sure the variables exist at all.
