In Disocrd.JS V.14, I am encountering a TypeError that says "Cannot read properties of undefined (reading 'leave')."

The given code implements a command that displays a dropdown menu containing all servers the bot has joined. Once the user selects a server, the bot asks if they want to kick it from that server. However, clicking the "Kick" button results in an error "Cannot read properties of undefined (reading 'leave')" in the terminal. The code also includes declarations for the bot's intents. Can anyone help me identify and fix the issue? Thank you in advance!

It seems like you are trying to implement a command that displays a dropdown menu containing all servers the bot has joined. Once the user selects a server, the bot asks if they want to kick it from that server. However, clicking the "Kick" button results in an error "Cannot read properties of undefined (reading 'leave')" in the terminal. This error is usually caused by trying to access an object property that does not exist or is undefined. It is possible that the bot is not connected to any server or that the server you are trying to kick does not exist. To fix this issue, you can try checking if the bot is connected to any server before attempting to kick it. You can also check if the server you are trying to kick exists before attempting to kick it. If you are still having trouble, you can try posting your code on a forum like Stack Overflow or GitHub and asking for help there. People there can help you identify and fix the issue. I hope this helps! Let me know if you have any other questions.

The error message suggests that the guild variable is undefined, which means that the guild object cannot be found by the guild.name property. This could be caused by several reasons such as the bot not being a member of the selected guild or the bot not having the necessary permissions to leave the guild. To avoid this error, you could add a null check to make sure that the guild variable is defined before calling its methods. Here's an example of how you can modify the code to add the null check: 
buttonCollector.on('collect', async (interaction) => {
    // Get the selected server and guild object
    const selectedServer = interaction.message.embeds[0].title;
    const guild = interaction.client.guilds.cache.find(guild => guild.name === selectedServer);

    // Check if the guild exists
    if (!guild) {
        return interaction.reply({ content: 'The bot is not a member of this server.' });
    }

    // Check if the bot has the necessary permissions to leave the guild
    if (!guild.me.hasPermission('KICK_MEMBERS')) {
        return interaction.reply({ content: 'The bot does not have the necessary permissions to leave this server.' });
    }

    // Leave the guild
    await guild.leave();

    // Reply to the interaction with a success message
    await interaction.update({ content: `The bot has been kicked from ${selectedServer}.`, embeds: [], components: [], ephemeral: true });
});
As for your intents, they seem to include all the necessary intents for your command to work correctly. You have included Guilds, GuildMembers, GuildMessages, MessageContent, DirectMessages, and GuildVoiceStates which are the recommended intents for most bots that require basic functionality.
