Ошибка обработки OpsWorks Berksfile: (Encoding :: InvalidByteSequenceError)

Несколько часов назад все мои стеки OpsWorks перестали работать. update_custom_cookbooks. Все они терпят неудачу при «Установить кулинарные книги, указанные в Berksfile и их зависимости» с ошибкой: в `encode ':" \ xC3 "в US-ASCII (Encoding :: InvalidByteSequenceError).

В нашем стеке OpsWorks используются экземпляры Chef версии 11.10, Berkshelf версии 3.1.3 и Ubuntu 14.04.

Berksfile: в целях тестирования я заменил наш обычный файл следующим, но все равно получаю ту же ошибку:

source "https://supermarket.getchef.com"

cookbook 'apt'

Вот часть журнала ошибок от OpsWorks:
