invalid URL?

[4chana]

i'm a total novice at this so i apologize if this has a simple answer, i keep getting "[ERR_INVALID_URL]" and can't figure out how to fix it:

Node.js v20.16.0
Myname-MacBook-Pro:plex-letterboxd myname$ node ./index.js --ip my.ip.address --username myname /Users/myname/Desktop/letterboxd.txt
Processing list "https://letterboxd.com/dave/list/official-top-250-narrative-feature-films/"

  code: 'ERR_INVALID_URL',
  input: 'http://myipaddress :32400/'
}

tried with different list URLs in the txt file and am getting the same results every time. any advice? thank you!
