The print method expects an array reference, not a hash reference:

use v5.12;
use warnings;

use Text::CSV_XS;

my $csv = Text::CSV_XS->new ({
    binary    => 1,
    sep_char  => ";",
    eol       => $/,
    auto_diag => 1,
    });

my @fields = qw( ID NAME INDICATOR VALUE CI_LOW CI_HIGH );
$csv->print (*STDOUT, \@fields);
say  '';

my @columns = @{$csv->getline (*DATA)};
$csv->column_names (@columns);

while (my $hr = $csv->getline_hr (*DATA)) {
    # my @nr = @{$hr}{'ID'};
    $hr->{ID} =~ s/12/Sun/g;
    $hr->{ID} =~ s/17/Moon/g;
            
    $csv->print (*STDOUT, [ map { $hr->{$_} } @columns ]);
    }

Much easier to read and much faster too would be to use bind_columns

my @fields = qw( ID NAME INDICATOR VALUE CI_LOW CI_HIGH );
$csv->print (*STDOUT, \@fields);

my @columns = @{$csv->getline (*DATA)};
my %rec;
$csv->bind_columns (\@rec{@columns});
while ($csv->getline (*DATA)) {
    $rec{ID} =~ s/12/Sun/g;
    $rec{ID} =~ s/17/Moon/g;
            
    $csv->print (*STDOUT, [ @rec{@columns} ]);
    }

update: I stripped the data sections from the code as they are identical to those in the OP and reduced the second example to show only the changed part.


Enjoy, Have FUN! H.Merijn
