message.mentions.users.first() 未定义 - discord.js

Question

const user = message.mentions.users.first();
console.log(user)

This is just a snippet of code, but the console outputs undefined. Above this is boilerplate command handler stuff. Other things work fine, but the message.mentions.users.first is the problem. I've tried almost everything from other questions like this. Any ideas?

Reginald is the role not a user that's why message.mentions gives you 'mentionable:false' check if there is role same name as 'Reginald'
