Here is how I solved it. I was missing a filter for my custom post type which I added to my “custom_setup” function.

add_filter('rest_prepare_custom_nav', function($response) {
     $response->data['acf'] = get_fields($response->data['id']);
     return $response;
});

So the filter is a wild card filter, applied like

apply_filter("rest_prepare_YOUR-CUSTOM-POST-TYPE-NAME-HERE", ...
