That's a cool name but it cannot be named that way for the machine url
[xUnit.net 00:00:00.90] MachineUrl/ModlistRepository is not valid! Allowed Characters are: 0-9, A-Z, a-z, _ and - use https://regex101.com/r/cVYtyA/2to test: "F.I.L.F.Y." ("F.I.L.F.Y.")

Recommended fix: since this is only used internally; "filfy" should be enough.

Let me know here when you've edited it

I have updated it to FILFY now. Thank you for explaining the issue. I'm new to anything to do with GitHub. :)
