Why can't SOAP::Lite deserialize its own output?

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello, perl 5.18.2 SOAP::Lite 1.11 I'm trying to use SOAP::Lite to deserialize its own output, but I get an exception. Can someone please suggest how I might change the serializer or deserializer to resolve this issue. Solutions that are likely to be compatible with other SOAP desierializers are preferred. Thank you!

$ cat test.pl
use strict;
use warnings;

use SOAP::Lite;

print "\$SOAP::Lite::VERSION: $SOAP::Lite::VERSION\n";

my $writer = SOAP::Serializer->new();
my $fault = SOAP::Fault->new(faultcode => "Server");
my $content = $writer->envelope(fault => $fault);

print $content, "\n";

eval {
    SOAP::Deserializer->deserialize($content);
};

if ($@) {
    print "Deserialize failed: $@";
}

$ perl test.pl
$SOAP::Lite::VERSION: 1.11

I am guessing that this line: `Argument "Server: " isn't numeric in sprintf at /home/vagrant/perl5/pe +rlbrew/perls/perl-5.18.2-fPIC/lib/site_perl/5.18.2/SOAP/Lite.pm line +1033` [download] is pointing to the culprit. Is `Server` the correct type of argument for `fault`? What happens if you change `my $content = $writer->envelope(fault => $fault);` [download] to this? `my $content = $writer->envelope(fault => '');` [download] You must always remember that the primary goal is to *drain the swamp* even when you are hip-deep in alligators.

Same exception if the faultcode is "" or 0.	[reply]

Look for `namesp1` in the docs for SOAP::Lite. There might be some info there for the error msg from the failed eval (especially in the sections on `use_prefix` and Disable use of explicit namespace prefixes.

SOAP is hard, good luck with that :) Why can't SOAP::Lite deserialize its own output? Can someone please suggest how I might change the serializer or deserializer to resolve this issue. I don't think you can blame SOAP::Lite here ... but I hate SOAP If you do things the way SOAP::Lite wants you to, it seems to work server output Read more... (1031 Bytes) client output (you can see the $fault is parsed without die-ing) Read more... (5 kB) soap-lite-server.pl Read more... (2 kB) soap-lite-client.pl Read more... (2 kB) Good luck with that :) Here is my copy/paste of my soap tips (I hate soap), SOAP::Lite is too much work, SOAP::Simple is less work (but its simple, when stuck go to XML::Compile::SOAP, more verbose, but you want verbose with SOAP ) ... its built on XML::Compile::SOAP/http://perl.overmeer.net/xml-compile/#doc , see my treasure trove of soap examples and lost knowledge,$soap->transport->add_handler("request_send", \&pp_dump );, http://cookbook.soaplite.com/, SOAP endpoint , Re^3: SOAP::Lite login setup, Re: I do not understand how to write a SOAP server., An XML Overview Towards Understanding SOAP, Re^3: SOAP::Lite and custom envelopes, The XML FIles: Understanding XML Namespaces, How to Call a .NET-based Web Service Using the SOAP::Lite Perl Library (2002 ) Good luck with that :)	[reply] [d/l] [select]
