Facing issue to run JavaScript file

I am facing issue to run the JavaScript file in VS code.
I am getting the output as:-
[Running] node "e:\n\Temporay folders of web development\vs code project\tut64.js"
node:internal/fs/utils:343
throw err;
^

}

And in the terminal I am getting:-

}
I am not getting what type of these errors are and why I am getting them.

In the terminal you should do node tut64.js
And check the path of tut64.txt or post your code.

What is this error that appears when executing my files?

Whats the problem ??? I'm working on a bot for discord using JavaScript when executing my files in VS code it works normally but in Repl.it it shows me this error

throw err;

starting a Discord Bot in heroku causes errors that i dont have when starting it from cmd

When I deploy the bot in Heroku, the build is successful, but then the bot crashes with this error in the log

Not sure what the error means or how to fix it. When I run it from my terminal the code works without any errors.
thanks in advance

how to connect nodejs application to google cloud mysql (no bs)

I've seen a ton of conflicting answers and I want this thread to be very conclusive. I'm running a Node.js app that needs to have a server endpoint to call a google mysql database.
The SQL call I'm making in server.js should be fine, empty though. Regardless, the break point isn't at the SQL call.
There's no enforced password set up so I have those credentials set up as
...
user: 'root',
password: '',
...
and I'm currently not using the socketPort configuration option.
Respond if you need any more information about the database.
This is a full stack trace, you can see it yourself by running npm run dev

Most likely your mysql server is not running, or running on a different port/interface.
