Yes, this is fixed in vdsm 4.18.21.

As a workaround, uncheck the "Require authentication" checkbox, but also
fill the user name and password fields with some strings. You don't have
to enter any real values. Using "abcd" or "12345" is OK, the values will
not be used during the import.

There's probably no need to open the bug. The error is harmless and we
already have a patch pending for that.
