Custom Endpoint 404

I’m using Beta 10, PHP 7 on localhost with MAMP

My permalinks are set to postname.

The standard endpoints users, posts, etc are working correctly.

I’ve added these two functions in order to get a list of the post ids through the endpoint ‘/post-ids’

I get the response returned:

{
“code”: “rest_no_route”,
“message”: “No route was found matching the URL and request method”,
“data”: {
“status”: 404
}
}

When I look at my namespaces I see my custom name space. I feel I’m close, but missing something small.

public function register_routes() {
				$version = '1';
				$namespace = 'wpapi-testing/v' . $version;
				$base = 'post-ids';
				register_rest_route( $namespace, '/' . $base, array(
							'methods'         => 'GET',
							'callback'        => 'my_awesome_func'
						)
					);
			}

	function my_awesome_func() {
	        $all_post_ids = get_posts( array(
	            'numberposts' => -1,
	            'post_type'   => 'post',
	            'fields'      => 'ids',
	        ));
		    return $all_post_ids;
	}
