Discord.js file error when activating multiple projects

I have a project and I plan to activate more than one bot in this project, but I encountered such a problem while activating my first bot.
Discord.js Version: 13.6.0
Node.js Version: v16.13.2
I leave the glitch project link.

This is because . matches to /app/botlar due to botlist2.js being executed in the file index.js. So for example you would need to do something like this:
fs.readdirSync('./botlar/botlist2/commands');

Any help will be really appreciated. I tried editing the file like many times and I failed all the time.

Install dotenv:
npm install dotenv
and add the line below at the beginning of your code:
require('dotenv').config()

Problem with node or my code, developing a discord bot

I am trying to code my own Discord Bot and I got an error that I am not able to solve:
internal/modules/cjs/loader.js:968
throw err;

}
And there is my code:
const Discord = require('discord.js');
const client = new Discord.Client();
const prefix = '-';
const fs = require('fs');
client.commands == new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
for(const file of commandFiles){
const command = require('./commands/${file}');
client.commands.set(command.name, command);
}
client.once('ready', () => {
console.log('Playlist is on!');
});
client.on('message', message =>{
if(!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).split(/ +/);
const command = args.shift().toLowerCase();
if(command === 'ping'){
client.commands.get('ping').execute(message, args);
} else if (command === 'hello'){
}
});
I tried a load of solutions but I haven't found anything to resolve it so it will really help me
btw sorry if my English is bad I'm not English
image of the code
Now i got this error
`client.commands.setTo(command.name, command);

To use template literals you must wrap your string in backticks, instead of quotes.
Change
const command = require('./commands/${file}');
To
const command = require(`./commands/${file}`);

Im creating a discord bot , and when i try to run it(using the command node . )

It keeps giving me an error that the module cant be found . I reinstalled node but it still gave me the same error , then i reinstalled discord.js but it was the same.
CODE:
const Discord = require('discord.js');
const client = new Discord.Client();
const token = '(actual token here)';
client.on('ready', () => {
console.log(`Logged in as ${client.user.tag}!`);
});
client.on('message', msg => {
if (msg.content === 'ping') {
msg.reply('Pong!');
}
});
client.login('token');

Is there a good way to surface error traces in production across event emitters / event loop boundaries?

Let's say I have:
const req = require('net').createConnection(80, 'localhost');
req.on('error', (error) => {
console.error(error) // handle somehow
});
If error event occurs, I get
{ Error: connect ECONNREFUSED 127.0.0.1:80
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1117:14)
errno: 'ECONNREFUSED',
code: 'ECONNREFUSED',
syscall: 'connect',
address: '127.0.0.1',
port: 80 }
In the terminal.
I'd like instead to see the full stack:
{ Error: connect ECONNREFUSED 127.0.0.1:80
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1117:14)
at Object.<anonymous> (/Users/aleksey/error-handing-example.js:2:7)

errno: 'ECONNREFUSED',
code: 'ECONNREFUSED',
syscall: 'connect',
address: '127.0.0.1',
port: 80 }
Note: I obtained the full trace artificially like this:
Error.captureStackTrace(this);
const req = require('net').createConnection(80, 'localhost');
req.on('error', (error) => {
error.stack += this.stack.replace(/^.+$/, '');
console.error(error) // handle somehow
});
I can't be doing this for all errors, as it's not sustainable
Is there a way to do this:
a. In a way that doesn't hurt production stability (longjohn claims that it's for development only)?
b. Automatically?

Here's a hacky thing I cooked up using async_hooks and overriding Error.captureStackTrace:
const ah = require('async_hooks');
const traces = new Map();
ah.createHook({
init(id) {
const _trace = {};
Error.captureStackTrace(_trace);
traces.set(id, _trace.stack.replace(/(^.+$\n){4}/m, '\n'));
},
destroy(id) {
traces.delete(id);
},
}).enable();
global.Error = class extends Error {
constructor(message) {
super(message);
this.constructor.captureStackTrace(this, this.constructor);
}
static captureStackTrace(what, where) {
super.captureStackTrace.call(Error, what, where);
const trace = traces.get(ah.executionAsyncId());
if (trace) what.stack += trace;
}
};
The gist is:
Keep a map of asyncId => traces
Override Error.captureStackTrace to use the trace from that asyncId on top of the original stack
Not sure about its performance limitations, bugginess, and robustness, but that's all I could come up with .
Now if I have:
const req = net.createConnection(8080);
req.once('error', err => {
console.error(err);
});
instead of
{ Error: connect ECONNREFUSED 127.0.0.1:8080
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1084:14)
I get
{ Error: connect ECONNREFUSED 127.0.0.1:8080
