1. Судя по стек-трейсу ошибки, ее вызывает гем vk-ruby, а не vkontakte_api. Попробовал тот же вызов у себя - все работает, возвращается урл для загрузки.
2. Не нужно передавать параметр access_token - просто @vk.photos.get_wall_upload_server(group_id: 78348415)
3. Пользуйтесь fenced code blocks из GFM.
