How can I add a role to a member - discord.js

Question

So I am trying to make a verify script so when a member join he/she has to write !verify and then he/she will get a rank on the discord so we won't get raided by bot's
const Discord = require("discord.js");
const bot = new Discord.Client();
module.exports.run = async (bot, message, args) => {
message.delete()
const member = message.author
let myRole = message.guild.roles.cache.get("791724979435470889")
if (!message.channel.name.startsWith(`⚜ʙɪᴇɴ`)) return message.channel.send(`you have already been verified`).then(msg => msg.delete({ timeout: 5000 }));
message.channel.send(`${member} have been verifyed`).then(member.roles.add(myRole).tehn(msg => msg.delete({ timeout: 5000 })));
}
module.exports.help = {
name: "verify" //Name of the command
}
And when I try this code out I get this error And I have tried to research it but I can't find anything on it
This is my error
message.channel.send(`${member} have been verifyed`).then(member.roles.add(myRole).tehn(msg => msg.delete({ timeout: 5000 })));

Answer 1

roles is a property of the GuildMember object. You are unable to add roles to a User object (AKA message.author that returns the user object of the author of a message). From that instance, we would simply want to instead use the member property of the message object, resulting in message.member.
Final Code
const Discord = require("discord.js");
const bot = new Discord.Client();
module.exports.run = async (bot, message, args) => {
message.delete()
const member = message.member
let myRole = message.guild.roles.cache.get("791724979435470889")
if (!message.channel.name.startsWith(`⚜ʙɪᴇɴ`)) return message.channel.send(`you have already been verified`).then(msg => msg.delete({ timeout: 5000 }));
message.channel.send(`${member} have been verifyed`).then(msg => msg.delete({ timeout: 5000 }));
member.roles.add(myRole)
}
module.exports.help = {
name: "verify" //Name of the command
}
