Ошибка Процессора Sitecore Cortex

Я пытался реализовать демо-версию Sitecore Cortex (https://github.com/adeneys/cortex-processing-demo).

     2019-06-26 19:41:47.743 +05:30 [Error] Error Executing worker. Task Id: 8d6646ab-4bcd-4c29-97c0-2e071d3a1af8.

Я добавил модель и выполнил шаги, перечисленные в репозитории, но на третьем этапе «Регистрация задач» последние две задачи не выполняются, и я получаю следующую ошибку в журналах механизма обработки.

Кто-нибудь еще сталкивался с этой проблемой?
