Why can't use async execute(interaction, client)

const { SlashCommandBuilder, EmbedBuilder, PermissionFlagsBits } = require('discord.js');
module.exports = {
userPerms: [],
botPerms: [],
data: new SlashCommandBuilder()
 .setName('add')
 .setDescription('Add someone to the ticket (Ticket Command) ')
 .setDMPermission(false)
 .addUserOption(option =>
  option.setName('target')
   .setDescription('Member to add to ticket')
.setRequired(true)),
async execute(interaction, client) {
//log
const commandName = "ADD";
client.std_log.error(client, commandName, interaction.user.id, interaction.channel.id);
const chan = client.channels.cache.get(interaction.channelId);
const user = interaction.options.getUser('target');
const userID = user.id;
let Support_Role;
function Fivem() {
      return Support_Role = client.ticket.FIVEM_TICKET.ROLE_SUPPORT.ID;
      }
      function Redm() {
      return Support_Role = client.ticket.REDM_TICKET.ROLE_SUPPORT.ID;
      }
    if (interaction.guild.id == client.ticket.FIVEM_TICKET.GUILDID) {
  Fivem();
 } else if (interaction.guild.id == client.ticket.REDM_TICKET.GUILDID) {
   Redm();
 } else {
   return;
 }
if (chan.name.includes('ticket')) {
   chan.edit({
     permissionOverwrites: [
          {
            id: userID,
            allow: [PermissionFlagsBits.SendMessages, PermissionFlagsBits.ViewChannel],

          {
