AAM_Service_Content::beforeDispatch fatal error

Hi there

Perry here from WP Google Maps, I hope this finds you well.

Your plugin binds a filter to rest_request_before_callbacks, which calls AAM_Service_Content::beforeDispatch

AAM_Service_Content::beforeDispatch will then try to access $attrs['callback'] as an indexed array.

Our plugin, for various technical reasons, passes a closure as the callback for many REST routes.

Because of this, your plugin will throw an exception at Content.php:258 when our plugin is active.

Could we ask that you make a small change here in order to accommodate plugins that pass closure functions into the REST API?

Our suggested fix would be

if(is_callable($attrs['callback']))
	$callback = $attrs['callback'];
else
	$callback = (!empty($attrs['callback'][0]) ? $attrs['callback'][0] : null);

Please let us know what you think.

Kind regards
– Perry
