I'm having a hell of a time trying to track down the reasons for this error.
I'm getting an error that looks like: Use of uninitialized value $buffer in concatenation (.) or string at /usr/share/perl5/Catalyst/Engine/CGI.pm line 220. If I'm using the HTTP.pm Engine, I get the same error, but with a different line number; in both cases, it's the line beginning with "$buffer" in the $self->write method, which looks like this in CGI.pm: --- around write => sub { my $orig = shift; my ( $self, $c, $buffer ) = @_; # Prepend the headers if they have not yet been sent if ( $self->_has_header_buf ) { $buffer = $self->_clear_header_buf . $buffer; } return $self->$orig( $c, $buffer ); }; --- I will say upfront that I don't know how to use the Perl debugger. I have tried a lot of way to isolate this, and just can't figure out what's causing it. It does not happen on certain requests; for example, if I deliberately enter an incorrect password on a login page, I don't get it. But it happens on almost all other requests; I don't see where in the bogus-login cycle I might be avoiding something that could short-circuit this. I've looked over my code fairly closely, and I can't detect the pattern, or see anything that could be causing this. I should also note that this doesn't appear to have any effect on my program; it "works" fine, I see all the pages, etc. I'd be grateful if anyone could explain to me what might be causing this, or where I can look to try to figure it out. This is on Cat 5.80005 on Debian, with all modules up to date. Thanks.
