3.21.0 throws NSInvalidArgumentException for currentDirectoryURL

[msunjo]

Hello, I was using danger-swift where I needed to change current working directory to parent directory. The command looks like this: danger-swift local --dangerfile <danger-file-path> --cwd ../ and it worked on version 3.20.0, but now it throws an exception. How should the path be passed now?

Error print:

OK, this is likely related to this diff #634 (cc. @417-72KI ) I think it might be task.currentDirectoryURL = URL(fileURLWithPath: FileManager.default.currentDirectoryPath), this should probably be task.currentDirectoryURL = URL(string: FileManager.default.currentDirectoryPath)!, or something like that, I will try to see if that is the issue today or tomorrow morning.
Worst case I will revert only that line
