Bug #18180 for Convert-ASN1: Decode Error not descriptive enough to determine cause of error

Hi, I am trying to decode some ASN1 using Convert::ASN1 (0.20 off CPAN) and am getting a decode error which is a bit too cryptic for me to understand. I am able to successfully decode this message under Javascript and C++, but was concerned that there may be some restriction in the ASN1 Perl decoder that I was unaware of. For instance the presence of an OPTIONAL field in the ASN1. The ASN1 definition is held in np_asn1.pm (attached). Error Message: decode error a0<=>02 20 2 np-hsap-cluster-id at /home/marhind1/usr/local/lib/perl5/site_perl/5.8.0/Convert/ASN1/_decode. pm line 107. $VAR1 = undef; decode error a0<=>02 20 2 np-hsap-cluster-id at /home/marhind1/usr/local/lib/perl5/site_perl/5.8.0/Convert/ASN1/_decode. pm line 107. ...propagated at ./asn1_test.pl line 17. Decode function (from np_asn1.pm): sub np_asn_decode($) { my $data = shift; my $asn = Convert::ASN1->new; $asn->prepare($NP_ASN_DATA); my $asn_msg = $asn->find("NP-Message-T"); my $charenc = hex2char($data); my $msg = $asn_msg->decode($charenc); print $asn_msg->error() if !defined $msg; return $msg; } String to decode: 303e300602010002010ba0341a064e4f49535932a003020100020100301e1a093138302e 34323433321a0732332e343536371a08333435362e3738390202012c Your input would be much appreciated.
