Perl Fastcgi - HTTP::Message content must be bytes at - perl

Question

I am getting the following errors:
[Fri Feb 19 08:55:41 2016] [error] [client 172.16.30.100] FastCGI:
server "/home/admin/soap/server.fcgi" stderr: HTTP::Message content
must be bytes at
/usr/local/lib/perl5/site_perl/5.8.9/SOAP/Transport/HTTP.pm line 317
[Fri Feb 19 08:55:41 2016] [error] [client 172.16.30.100] FastCGI:
incomplete headers (0 bytes) received from server
"/home/admin/soap/server.fcgi" [Fri Feb 19 08:55:41 2016] [warn]
FastCGI: server "/home/admin/soap/server.fcgi" (pid 45466) terminated
by calling exit with status '255'
Here is line 317 of HTTP.pm I appreciate any input on a fix.
$self->response(HTTP::Response->new(
$code => undef,
HTTP::Headers->new(
'SOAPServer' => $self->product_tokens,
$compressed ? (
'Content-Encoding' => $COMPRESS) : (),
'Content-Type' => join(
'; ',
'text/xml',
!$SOAP::Constants::DO_NOT_USE_CHARSET && $encoding ? 'charset=' . lc($encoding) : ()
),
'Content-Length' => SOAP::Utils::bytelength $response),
$response,
));
$self->response->headers->header('Content-Type' => 'Multipart/Related; type="text/xml"; start="<main_envelope>"; boundary="'.$is_multipart.'"') if $is_multipart; }

Error message is pretty much telling you all about it: content for HTTP::Response object that you provide with $response variable must be bytes - i.e. a buffer without any characters outside 0-255 range. Use Encode::encode to transform it from Perl internal representation to whatever encoding required for your protocol.
By the way, this has nothing to do with fastcgi. The first error cause the script to die without emitting a response, resulting in the second error message.
