[midPoint] Value of attribute '_NAME_'must be a single value, but it has nullvalues

[Gus Lou]

I'm doing a proof of concept with Midpoint 4.1
I configured a resource with a CSV connector (I tested versions 2.3 and 2.4
of the connectors)
My CSV file has the following fields:
login (linked to midpoint field name)
func_num_cpf (linked to midpoint employeeNumber) it is Unique attribute name

Whenever I add or modify a record in my csv file, I get the following error
when executing the task:

*Value of attribute '_NAME_'must be a single value, but it has nullvalues*

I have already remade the settings, I searched the forum for something
similar, but I didn't find it. I know the error message is very clear, but
I don't know what else to do.
I attached my resource settings and csv file if anyone can help. I
appreciate any help

Best Regards
Gus
