ConversionException with Retrofit и Gson

Question

Я работаю с Retrofit и Gson Converter, но получаю это странное исключение. Для выполнения вызова я использую два URL-адреса. В обоих случаях я делаю тот же вызов и получаю тот же ответ на уровне полного журнала, но один из URL-адресов дает мне это исключение, и я не могу разобрать данные во втором случае.

Использование Retrofit v1.9 и Gson v2.6.1.

Спасибо!
