In a small application I was writing I had an error. The code looked like this: use File::Slurp qw(read_file); get '/' => sub { my $path = config->{appdir} . '/data.json'; my $posts; if (-e $path) { $posts = from_json read_file $path ; } template 'index', { posts => $posts }; }; The problem was that read_file was called in LIST context instead of SCALAR context which made the JSON incorrect and passed strange parameters to the from_json call. I solved it now BUT This is the error I got from Dancer. This does not mention my code at all. It jumps from app.pl to Dancer.pm hich is not good IMHO.
