This error wasn't a problem until today. Every time I would run my discordjs bot, it gives me a TypeError saying "Cannot read properties of undefined (reading 'toLowerCase')"
Heres my code
const { readdirSync } = require('fs');
const { Collection } = require('discord.js');
client.commands = new Collection();
const events = readdirSync('./events/').filter(file => file.endsWith('.js'));
console.log(`Loading events...`);
for (const file of events) {
const event = require(`../events/${file}`);
console.log(`-> Loaded event ${file.split('.')[0]}`);
client.on(file.split('.')[0], event.bind(null, client));
delete require.cache[require.resolve(`../events/${file}`)];
};
console.log(`Loading commands...`);
readdirSync('./commands/').forEach(dirs => {
const commands = readdirSync(`./commands/${dirs}`).filter(files => files.endsWith('.js'));
for (const file of commands) {
const command = require(`../commands/${dirs}/${file}`);
console.log(`-> Loaded command ${command.name.toLowerCase()}`);
client.commands.set(command.name.toLowerCase(), command);
delete require.cache[require.resolve(`../commands/${dirs}/${file}`)];
};
});
when I run the bot, the output goes like this
Loading events...
-> Loaded event interactionCreate
-> Loaded event messageCreate
-> Loaded event ready
Loading commands...

That means your commands (importing files) not all have the same structure (with property 'name') in it.
If the commands without name are not critical, you can filter out them:
for (const file of commands) {
const command = require(`../commands/${dirs}/${file}`);
if (!command || !command.name) {
console.warn(`Name is missing in 'commands/${dirs}/${file}'`)
continue;
}
console.log(`-> Loaded command ${command.name.toLowerCase()}`);
client.commands.set(command.name.toLowerCase(), command);
delete require.cache[require.resolve(`../commands/${dirs}/${file}`)];
};
Since I don't have an access to your file systems I can not see what content of the files is. But I assume the name is just missing in some of the file (command).
