FullCalendar прерывистая ошибка загрузки на Salesforce 1

Question

Я использую Полный календарь и у меня есть страница visualforce, которая включена для Classic и Salesforce 1, она отлично работает на Classic, но иногда наши инженеры сообщают, что они ошибаются при попытке загрузить страницу или при нажатии на одна из ссылок на записи на странице.

Ошибки: нетто: err_blocked_by-_Resource а также ошибка анализа ответа json 'Неожиданный токен <' вошли в систему? не определен </p>

Поскольку это временная проблема, я не могу отладить ее вообще. Мне было интересно, если кто-нибудь может предложить какое-либо понимание ошибок? Мой код ниже.
