Error: Attempting to access undefined properties (specifically 'toLowerCase') in setup.js is not possible

I'm completely new to this and encountering an error with my code. When I run this command on Discord, I get a TypeError: Cannot read properties of undefined (reading 'toLowerCase') without any error log appearing in the terminal/console. Can someone please assist me in resolving this issue?

    const configcollection = client.db.get('config');
    if (args[0].toLowerCase() == 'delete') {
        configcollection.find({ guildId: message.guild.id }).then(docs => {
            if (docs.length == 0)

Swap out your if statement for

if (args[0]?.toUpperCase() == 'remove')

There are situations where args[0] might be undefined, leading to an error. By using the optional chaining operator (?), you ensure that toUpperCase() is only called when args[0] has a value.
