How do I unban user with commands using Autocode?

Question

I don't understand what's wrong with my coding but when I try to unban someone it doesn't work.

I have configured the bot to unban a member with an id but it doesn't work.

When I try the command but putting the username of the concerned member, the bot sends me an error message like "Invalid command, use: w!unban <user ID>". This is normal because I configured it so that it sends this message when the command has been written wrong. However, when I do the command with the ID, I have no error message as if it had worked, but yet the member is not unbanned.

// Secret Token
const lib = require('lib')({token: process.env.STDLIB_SECRET_TOKEN});

// Check to see if guild is using prefix commands
let CommandType = process.env.COMMANDTYPE;
if (CommandType === 'prefix' || CommandType === 'both') {
  
  // Checks to see if the message starts with (prefixunban)
  let message = `${context.params.event.content}`;
  if (message.startsWith(`${process.env.COMMANDPREFIX}unban`)) {
    
    // Retreive the user that triggered the command
    let serverMember = await lib.discord.guilds['@0.1.0'].members.retrieve({
      user_id: `${context.params.event.author.id}`,
      guild_id: `${context.params.event.guild_id}`,
    });
    
    // Gets guild owner
    let guild = await lib.discord.guilds['@0.1.0'].retrieve({
      guild_id: `${context.params.event.guild_id}`,
    });
    let guildOwner = guild.owner_id;


    // checks to see if you have access to the command
    if (
      serverMember.roles.includes(`${process.env.ADMINROLE}`) ||
      context.params.event.author.id === guildOwner
    ) {
      
      // Gets the Current Time
      const now = new Date();
      const m = now.getMonth() + 1; // 0 index based
      const d = now.getDate();
      const h = now.getHours();
      const min = now.getMinutes();

      const dateText = `${m}/${d}, ${h}:${min}`; // -> "6/6, 15:19"


      // Tests to make sure that the message follows the right format
