Failed to deserialize content: Class::XSAccessor: invalid instance method invocant: no hash ref supplied at C:/Strawberry/perl/site/lib/Dancer2/Core/Role/Serializer.pm line 71.

Getting this error trying to deserialize an 'axios' call :

Failed to deserialize content: Class::XSAccessor: invalid instance method invocant: no hash ref supplied at C:/Strawberry/perl/site/lib/Dancer2/Core/Role/Serializer.pm line 71.

This is the dumped headers:

Headers: bless({
"accept" => "application/json, text/plain, /",
"accept-encoding" => "gzip, deflate, br",
"accept-language" => "en-US,en;q=0.8",
"connection" => "keep-alive",
"content-length" => 123,
"content-type" => "application/json",
"dnt" => 1,
"host" => "localhost:5000",
"origin" => "http://localhost:5000",
"referer" => "http://localhost:5000/net/add/switch_end_point",

}, "HTTP::Headers::Fast")

This is the 'request->content' (which I was able to deserialize using 'from_json()':

""name":"test","device":"one","slot":"two","port":"three","interface_type":"four","description":"five","switch_type":"six"}"

I am using the latest versions of both Dancer2 and Dancer2::Plugin::REST

Can you provide us with a minimal example of an application that reproduce the problem you're seeing?

`package Updates;
use Dancer2 appname => 'NetworkApp';
use Data::Dump qw/dump/;
use FindBin qw/$Bin/;
use Dancer2::Plugin::REST;

prepare_serializer_for_format;

prefix q{/add} => sub {

post q{/switch_end_point.:format} => sub {
    debug qq{Post: Adding a new switch end_point};
	my %in_param = params('body');   # fails
    # my %in_param = %{from_json( request->content ) // {}};  #  works

    if ( keys %in_param ) {
        debug qq{Got switch end_point params: } . dump( \%in_param );
    }
    else {
        my %e;
        $e{name} = ["Missing name"] unless $in_param{name};
        $e{interface_type} = ["Missing interface type"]
          unless $in_param{interface_type};
        error qq{Returning Errors: } . ( dump \%e );
        return status_422( \%e );
    }

    status_created(
        {
            message => [
                qq{ 
                     Created a new switch end_point with name, '$in_param{name}'
                      and interface '$in_param{interface_type}'
                 }
            ]
        }
    );

};

};`

---- Calling App

axios({ method: requestMethod, url: '/net/add/switch_end_point.json', /* 'data' from DevTools console: {name: "test", device: "one", slot: "two", port: "three", interface_type: "four", …} */ data: this.data() }) .then( response => { this.onSuccess(response.data); resolve(response.data); }) .catch( error => { this.onFail(error.response.data); reject(error.response.data); });

Or: I have a test repo in my GitHub account that worked when I tested it 6 months ago. Sorry

Awesome! Thanks!
