Hello Monks,
I have an issue where I am trying to check JSON decoded data from Dancer params. My module has something like this: 

use strict;
use warnings;
use Dancer;
use JSON qw(decode_json);

my $foo_info = param('foo_info');
if ( !eval { decode_json($foo_info); 1 } )  {
    flash error => "Failed"
}

if ( !exists $foo_info->{foo_total}
    || !($foo_info->{foo_total} =~ m/^\$\d+\.\d{2}$/)) {
        error("Invalid or missing foo info");
        return 0;
}

And the errors that I am getting are: 
Error decoding json data:
 malformed JSON string, neither tag, array, object, number, string or 
+atom, at character offset 0 (at the line I'm decoding the json)
request to POST /path/to/site crashed: Can't use string .. (json data 
+spit out here) as a HASH ref

So my problem may be 2 fold, but I do know I need help checking the values in the JSON 'foo_info' ..Any insight is greatly appreciated :)
