.users.cache.size not working with Discord.js bot

I have a problem with just a bit of my code:

<Client>.users.cache.size

It was working perfectly before but one day it begins to give me random numbers instead of the number of users the bot.

So I would like to fix this but I didn’t find how.

Answer

Try this, it is working:

<Client>.guilds.cache.reduce((a, b) => a + b.memberCount, 0)
