My bot says it doesnt have permissions to kick/ban - node.js

Question

I am making a Discord bot in js. Yesterday i finished some work on the bot's ban command and it worked normally. Today I wake up, don't modify anything and when I try it again, it says that it does not have permission. Nothing was changed and noone changed the permissions of the bot, it still has administrator. The error message:
(node:2490) UnhandledPromiseRejectionWarning: DiscordAPIError: Missing Permissions
at RequestHandler.execute (/home/runner/AUN/node_modules/discord.js/src/rest/RequestHandler.js:154:13)
at processTicksAndRejections (internal/process/task_queues.js:97:5)
at async RequestHandler.push (/home/runner/AUN/node_modules/discord.js/src/rest/RequestHandler.js:39:14)
My code is (a bit long):
const Discord = require("discord.js");
const dp = require('discord-prefix');
const lang = require('../language_manager');
const settings = require('discord-server-settings');
module.exports = (message, client) => {
if (!message.member.permissions.has("BAN_MEMBERS")) return message.reply("You do not have the permission to ban users");
if (!message.guild.me.hasPermission("BAN_MEMBERS")) return message.reply("I do not have permission to ban users");
let prefix = dp.getPrefix();
if(dp.getPrefix(message.guild.id)){
prefix = dp.getPrefix(message.guild.id);
}
var langchar = settings.getSetting('lang', message.guild.id)
const args = message.content.slice(prefix.length).trim().split(' ');
const command = args.shift().toLowerCase();
var noerror = true;
const member = getUserFromMention(args[0]);
const reason = args[1] || lang.get('ban_no_reason', langchar);
const embed1 = new Discord.MessageEmbed()
.setAuthor('AUN', 'https://drive.google.com/uc?export=view&id=129_JKrVi3IJ6spDDciA5Y5sm4pjUF7eI')
.setTitle(lang.get('ban_title', langchar))
.setColor('#ed3f2c')
.setDescription(lang.get('ban_noone_banned', langchar))
.setTimestamp()
.setFooter('Ping: ' + client.ws.ping + ' | '+prefix+command);
const embed = new Discord.MessageEmbed()
.setTitle(lang.get('ban_you_title', langchar))
.setAuthor("AUN", "https://drive.google.com/uc?export=view&id=129_JKrVi3IJ6spDDciA5Y5sm4pjUF7eI")
.setColor(0x00AE86)
.setDescription(lang.get('ban_you_part1', langchar)+message.guild.name+lang.get('ban_you_part2', langchar)+message.member.name+lang.get('ban_you_part3', langchar)+reason)
.setFooter("Ping: "+client.ws.ping+" | AUN discord bot")
.setTimestamp();
if (!member) {
embed1.setTitle(lang.get('ban_error', langchar))
.setDescription(lang.get('ban_no_mention', langchar))
.setColor('#bd1300');
noerror = false;
}
if(noerror){
embed1.setDescription(lang.get('ban_banned_part1', langchar)+member.tag+lang.get('ban_banned_part2', langchar));
member.send(embed);
}
message.channel.send(embed1);
try{
return message.guild.member(member).ban();
}catch (e){
return;
}
function getUserFromMention(mention) {
if (!mention) return;
if (mention.startsWith('<#') && mention.endsWith('>')) {
mention = mention.slice(2, -1);
if (mention.startsWith('!')) {
mention = mention.slice(1);
}
return client.users.cache.get(mention);
}
}
}
Please if you have any idea what is going on, tell me

You should check if you can actually ban the member.
You can check this with
