Trying to create a channel under a category

client.on('guildMemberAdd', async member => {
    const guild = member.guild;

  // Find the verification category by name (case-insensitive)
  const verificationCategory = guild.channels.cache.find(channel => channel.type === 'GUILD_CATEGORY' && channel.name.toLowerCase() === 'verification');

  if (!verificationCategory) {
    console.error('Verification category not found.');
    return;
  }

  const everyoneRole = guild.roles.everyone;

    try {
        // Create a private channel for the user under the verification category
        const channel = await guild.channels.create({
            name: `verification-${member.user.username}`,
            type: 'text', // Text channel
            parent: verificationCategory, // Set the verification category as the parent

//More code after this but I've tested it and it works. The error only happens when trying to set the parent:
