you can try this to remove the error.

$SIG{__WARN__} = sub {
  my $wn = shift;
  return if $wn =~ /Use of uninitialized value/i;    #Most annoying
  warn $wn;
};

Good Luck^^

*Edited if you still have problems try this.

BEGIN {
$SIG{__WARN__} = sub {
  my $wn = shift;
  return if $wn =~ /Use of uninitialized value/i;    #Most annoying
  warn $wn;
};
}
