Hi, here is what I'm trying to do:

package mbf;
use Dancer2;
use Dancer2::Plugin::REST;
prepare_serializer_for_format;

get '/page.:format' => sub { [
        'some key' => 'value',
        'something'=> 'else',
    ] };
true;

And when I go to http://localhost:5000/page.json I get ARRAY(0x23b3880) in the browser. The data was not serialized.
What did I do wrong?

As an alternative I've done something that works:

package mbf;
use Dancer2;
use Dancer2::Serializer::JSON;

get '/page.json' => sub {
    to_json([
        'some key' => 'value',
        'something'=> 'else',
    ]);
};
true;

And in the browser I get what I expect: ["some key","value","something","else"]

I would like to use use Dancer2::Plugin::REST though, to leave the choice of format to whoever will use the API.

I noticed a detail in the module's documentation. The two examples given are:

    get '/user/:id.:format' => sub {


and


    get qr{^/user/(?<id>\d+)\.(?<format>\w+)} => sub {

The first example is similar to my case, but not the second one. And the documentation says: "Regexp routes will use the file-extension from captures->{'format'} to determine the serialization format." Which seems to indicate that only the second use case in the documentation would work.  I tried it. It didn't work for me either. I must be doing something wrong.
Any idea?
