Ошибка загрузки асаны с асаной / php-asana

пытаемся проверить предоставленный пример кода:

$attachment = $client->attachments->createOnTask(
$enquiry->id,
'hello word',
'upload.txt',
'text/plain'
);

Ошибка:
400 File is not an object

Клиент определенно работает (умеет создавать задачи только раньше).
TaskId ($enquiry->id) правильно (проверено, перейдя в URL и т. д.).

Использование v0.4.0 библиотеки и PHP 5.6.18-1 на виртуальной машине Homestead.

Подобные вопросы на SO говорят о плохом кодировании, но в моем случае все кажется нормальным.
