but only one warning is comming out everytime

the line 85 being marked with **** 

my $cChipId;
my $cSubVersId;
my %data_ids;
my $readline;
if(open (my $CFILE,"config.txt" ) || die "couldnt open file:", $! ) {
   while ($readline = <$CFILE>) {
       chomp $readline;
       my ($key , $value) = (split /::/, $readline);
       $data_ids{$key} = $value;****
   }
  
   for my $key (keys %data_ids) {
       $cChipId = $data_ids{'chipid'};
       $cSubVersId = $data_ids{'subversid'};
   }
}
