It’s kinda hard to tell what you ran from you pasted, but I think you’re mistakenly passing the src and target as a single argument. They are two separate arguments, which means two sets of quotes. (generally, though, quotes are not required for the target because targets will not contain spaces or any other characters that need to be quoted)
If you can share the entire command you’re running along with the error message I can probably point you in the right direction. Thanks
