const unbanUserId = interaction.options.getString('user_id')

  try {
      const getGuildBanList = await interaction.guild.bans.fetch()
      const checkTheUserStated = getGuildBanList.get(unbanUserId).user

    if (checkTheUserStated) {
       await interaction.guild.members.unban(unbanUserId)
        const unBannedEmbed = new MessageEmbed()
        .setColor('PURPLE')
        .setTitle('User unbanned')
        .setDescription(`Successfully unbanned <@!${unbanUserId}>`)

        return interaction.editReply({ embeds: [unBannedEmbed] })
    } else {
        const notBanned = new MessageEmbed()
        .setColor('PURPLE')
        .setDescription(`The stated user is not banned.`)

        return interaction.editReply({ embeds: [notBanned] })
    }
  } catch(e) {
      console.log(e)
  }

I am trying to make it so that when the user isn't banned that it will return a simple embed but it seem just too keep returning Cannot read properties of undefined (reading 'user')
