Trouble using tool posted on GitHub

I downloaded this tool called XAttacker by a guy called Moham3dRiahi. You are supposed to run it with a list of websites. Although you are supposed to be able to run it without one and then enter the website during the program. Well, it said on line 102 it couldn’t open the website list. So, I ran it with a file filled with websites. Got the same issue. Does anybody know how to fix it? I downloaded it on the Ubuntu Sub-System for Windows-10. This is the error I keep getting:

[-] Can't open the list websites file at line 102.

Hope you can find the fix for this.

If you’re asking how to use the piece of software that you found in a repository on GitHub, the best way to contact the maintainers of that software is to:

  1. Check the README for instructions on how to operate the software, pointers to documentation or troubleshooting info.
  2. Check the SUPPORT file, if one exists for instructions on how to best contact the maintainers for support.
  3. Check the CONTRIBUTING guide, if one exists. Sometimes if there isn’t a SUPPORT file, the CONTRIBUTING guide will give instructions on how to contact the maintainers for support.

All of these documents can be found, if they exist, in the repository where you found the software itself.

I hope that helps!
