[midPoint] CSV connector - exception during import

[kir.blood at gmail.com]

Hi all,
I use docker image `evolveum/midpoint:4.1`. When I try to import user from
csv resource, I get a error 'Value of attribute '__NAME__' must be a single
value, but it has nullvalues'. But ri:Number that represent __NAME__ is not
null. I used different csv files with different formats, but I got this
error in all cases.
I have attached resource XML, CSV file and logs.
I will really appreciate if anyone help me with this issue.
Regards,
Kirill
