get_posts returning empty array

Question

I am building a custom WordPress function/plugin that uses get_posts. The following code returns an empy array. I have included wp-load.php in my script. Is there something else I am missing?

$args = array(
    "posts_per_page"   => -1,
    "paged"            => 0,
    "orderby"          => "post_date",
    "order"            => "DESC",
    "post_type"        => "carellcars, ccf, attachment",
    "post_status"      => "publish, inherit",
    "post_author"       => "2"

);

$posts_array = get_posts($args); 

print_r($posts_array);

die;

If I use arrays for post_type and _status the array is not populated, but if I use single values for post_type and _status the array is populated?

Not populated:

$args2 = array(
    'posts_per_page'   => -1,
    'paged'            => 0,
    'orderby'          => 'post_date',
    'order'            => 'DESC',
    'post_type' => array('carellcars', 'ccf', 'attachment'),
    'post_status'      => array('publish', 'inherit')
);

Populated:

$args2 = array(
    'posts_per_page'   => -1,
    'paged'            => 0,
    'orderby'          => 'post_date',
    'order'            => 'DESC',
    'post_type' =>  'carellcars',
    'post_status'      => 'publish'
);

Update, removing "ccf" post type produces results, but I do have a ccf post_type and would like to include them. Any ideas?

    'post_type' => array('carellcars', 'attachment'),
    'post_status'      => array('publish', 'inherit')

Try

"post_type" => array('carellcars', 'ccf', 'attachment'),
