k8s_collect.pl doesn't report metrics from nodes

[nitrogear]

Following loop collects metrics from all items with namespace:

        # if element has namespace, check if we really need this one and if its equal to current item
        if (defined $element->{metadata}->{namespace}) {
            next unless (
                defined $NAMESPACES_HASH{$element->{metadata}->{namespace}}
                and $element->{metadata}->{namespace} eq $namespace
            );
        }

        next unless ($element->{metadata}->{name} eq $name);

However node metrics don't have namespace, that's why collect script doesn't report any metric from nodes
