Hey there! Thanks for taking interest in this project.

Whats username and password defined as? Username and password need to strings, and a valid login. If you don't have a minecraft account or need to play offline, remove the password field.

I solved the problem but now it's giving me this error: TypeError: Path must be a string. Received undefined

[Pierce01]

can you give me the full stack trace (as in the error)?

I'm pretty sure you're just leaving it undefined

Closing since user hasn't responded. Assuming they've solved it
