cnf-init выдает ошибку Python в ubuntu ami

Question

Я использую приведенный ниже шаблон облачной информации aws, чтобы развернуть группу автомасштабирования, и он выдает ошибку python, когда я пытаюсь запустить cfn-init. Я перепробовал все, что мог придумать, чтобы решить эту проблему, но теперь я полностью озадачен. Я получаю следующее сообщение об ошибке:

Error occurred during build: list indices must be integers, not unicode

Это мой шаблон Cloudformation:

Любая помощь или направление в правильном направлении было бы замечательно. Я пробовал использовать разные версии aws -cfn- bootstrap, но все они вызывали у меня одну и ту же проблему.
