Почему происходит ошибка "ktor client error serialization illegal input" при сериализации JSON?

Подскажите пожалуйста, в чём может быть ошибка? У меня есть два дата класса для получения и серилизации JSON. При выполнении кода возникает ошибка:

Exception in stream "main" io.ktor.serialization.JsonConvertException: Invalid input Thrown: 
kotlinx.serialization.json.internal.JsonDecodingException: Expected object 
start '{' but got 'EOF' instead at path: $JSON input: . ....-21T01:41:59.300Z","created_at":"2023-02-21T01:41:59.300Z"}]

Вот код:
