Slightly different error but a quick google search turned it up 😊
ive done this one and it did nothing
i have nothing to change from what ive input though
it was working fine and dandy
until i changed the token of the dotenv + the name of the project
Is it definitely getting your token from your .env file? Try console.log the token
