Could some one point me to at what I'm doing wrong in the config.yml? I'm following the tutorial and the advent stuff and trying to enable plack_middlewares. Here's my config.yml layout: "main" charset: "UTF-8" template: "template_toolkit" engines: template_toolkit: encoding: 'utf8' start_tag: '[%' end_tag: '%]' log: 'debug' show_errors: 'true' plack_middlewares: Debug: - panels - - Memory - DBITrace - Timer Here's the error message when I plackup $ plackup -S Starman --workers=10 -p 5000 -a bin/app.pl Error while loading bin/app.pl: Unable to parse the configuration file: /opt/foobar/webapps/cemconf/config.yml: Died at /usr/local/share/perl/5.10.0/YAML/Loader.pm line 676, <$IN> line 1. at /usr/local/share/perl/5.10.0/Dancer/Config.pm line 177 Dancer::Config::load_settings_from_yaml('/opt/foobar/webapps/cemconf/config.yml') called at /usr/local/share/perl/5.10.0/Dancer/Config.pm line 159 Dancer::Config::load('Dancer::Config') called at /usr/local/share/perl/5.10.0/Dancer.pm line 225 Dancer::import('Dancer') called at bin/app.pl line 2 Plack::Sandbox::bin_2fapp_2epl::BEGIN() called at /usr/local/share/perl/5.10.0/Dancer.pm line 2 eval {...} called at /usr/local/share/perl/5.10.0/Dancer.pm line 2 require bin/app.pl called at (eval 8) line 3 eval 'package Plack::Sandbox::bin_2fapp_2epl; { my $app = do $_file; if ( !$app && ( my $error = $@ || $! )) { die $error; } $app; } ;' called at /usr/local/share/perl/5.10.0/Plack/Util.pm line 108 Plack::Util::_load_sandbox('bin/app.pl') called at /usr/local/share/perl/5.10.0/Plack/Util.pm line 124 Plack::Util::load_psgi('bin/app.pl') called at /usr/local/share/perl/5.10.0/Plack/Runner.pm line 173 Plack::Runner::__ANON__() called at /usr/local/share/perl/5.10.0/Plack/Runner.pm line 23 Plack::Runner::__ANON__() called at /usr/local/share/perl/5.10.0/Plack/Runner.pm line 23 Plack::Runner::__ANON__() called at /usr/local/share/perl/5.10.0/Plack/Runner.pm line 23 Plack::Runner::__ANON__() called at /usr/local/share/perl/5.10.0/Plack/Runner.pm line 23 Plack::Runner::__ANON__() called at /usr/local/share/perl/5.10.0/Plack/Loader.pm line 56 Plack::Loader::preload_app('Plack::Loader=HASH(0x91d2550)', 'CODE(0x93054e0)') called at /usr/local/share/perl/5.10.0/Plack/Runner.pm line 253 Plack::Runner::run('Plack::Runner=HASH(0x9119bf0)') called at /usr/local/bin/plackup line 10 BEGIN failed--compilation aborted at bin/app.pl line 2.
