Youtube notification discord bot

So I have some code which makes the bot send the link of my video when I upload something, but it gives me an error when I run it. Pls help
Repl link:

 npm start
npm ERR! missing script: start

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/runner/.npm/_logs/2023-08-15T15_25_41_480Z-debug.log
exit status 1

It seems that you are running npm start. You can Run the Repl by pressing the Run button instead. It seems to be that npm start giving the error.

Try npm run start instead, as I believe that’s the default.

Why? Isn’t it better just to press the Run button?

Possibly, though that should have the same effect here.
