While trying to deploy an application I've just encountered this error:

error @2015-09-24 09:06:31> Route exception: Undef did not pass type constraint "Str" (in $args->{"name"}) at (eval 663) line 192 "Str" is a subtype of "Value" "Value" is a subtype of "Defined" Undef did not pass type constraint "Defined" (in $args->{"name"}) "Defined" is defined as: (defined($_)) in /home/user/perl5.22.0/lib/site_perl/5.22.0/Dancer2/Core/App.pm l. 1276

I don't see this on my development machine and so far I have no idea where to look.

Before I go down the rabbit hole trying to find the differences and the source of the problem, I wonder if anyone has encountered this.

Dancer2 0.162 on both machines: dev using plackup 1.0037 prod using Starman 0.4014

Dancer2::Plugin::Auth::Extensible 0.401

regards Gabor

I tried using plack on the server and it work properly. It also seems to work well when I run

plackup -s Starman -p 3000

So it seems this is something related to how I run Starman which is by way of this script launched from /etc/rc.local

#!/home/user/perl5.22.0/bin/perl use warnings; use strict; use Daemon::Control;

use File::Basename qw(dirname); use Cwd qw(abs_path);

Daemon::Control->new( { name => 'Starman', lsb_start => '$syslog $remote_fs', lsb_stop => '$syslog', lsb_sdesc => 'Starman Short', lsb_desc => 'Starman controls the web sites.', path => abs_path($0),

program => dirname($^X) . '/starman',

program_args => [ '--workers', '5', '--port', '3000', '/home/user/work/app/app.psgi' ],

pid_file => '/tmp/starman.pid', stderr_file => '/tmp/starman.err', stdout_file => '/tmp/starman.out',

fork => 2,

} )->run;

Oh and I am using perl 5.22.

OK I found the source of this error. I have put the mongodb configuration parameters in the environment/development.yml which worked every time I used plack, but when I launched Starman directly then it was using a differetn environment (deployment if I am not mistaken). The solution was to add $ENV{DANCER_ENVIRONMENT} = 'production'; to the code launching Starman and add the appropriate mongodb configuration options to the environment/production.yml file. Now I just wonder if Dancer could have provided me with a better error report? Gabor
