I'm getting TypeError [ERR_INVALID_URL]: Invalid URL

[Roboticol]

I was trying to run this code and got this error, anyone knows how to fix this:

node:internal/url:552
  throw new ERR_INVALID_URL(input);
  ^

TypeError [ERR_INVALID_URL]: Invalid URL

    at node:internal/main/run_main_module:17:47 {
  input: 'undefined',
  code: 'ERR_INVALID_URL'
}

Btw I used node "d:\profitable_flashloans\run-arbitrage.js" to run the program
