Drupal 7 Services -- hook_services_request_postprocess_alter() does not identify the requested resource
if you take a look to $args array, you can find your node type, for example I have a content type "video", my $args are like this:

Array
(
    [0] =&gt; 2
    [1] =&gt; *
    [2] =&gt; Array
        (
            [type] =&gt; video
            [uid] =&gt; 92
        )

    [3] =&gt; 2
)


Then $args[2] has the content type (because I set it like a parameter in my resource:
http://site.local/api/v1/node?parameters[type]=video&amp;parameters[uid]=92&amp;pagesize=2&amp;page=2
