I don’t use any Sharepoint back end, but with your help I found the solution.
OneDrive for Business uses SP, so I changed my destination to “OneDrive v2” and of course, corrected the path and the problem is gone. BTW I saw a warning with ignored options -auth-name and -auth-pass, but after I changed to “OneDrive for Business” again and deleted login and pass and returned to “OneDrive v2” the warnings were gone too.
