Ошибка: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 14 path

учусь пользоваться retrofit, тренируюсь на API vk.com, получаю вот такую ошибку:

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 14 path $.response
 at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory$ ...blablablabla

Не могу найти где проблема, кто-нибудь сможет подсказать где ошибка и как пофисксить? Буду благодарен.

Code in VkPagingSource:

class VkPagingSource(
    private val vkApi: VkApi,
    private val userId: String
) : PagingSource<Int, VkPerson>() {

    override suspend fun load(params: LoadParams<Int>): LoadResult<Int, VkPerson> {
        val position = params.key ?: VK_STARTING_PAGE_INDEX

        return try {
            val vkResponse = vkApi.searchFriends(userId, "500", "city,domain,photo_100", VkApi.API_VERSION, VkApi.ACCESS_TOKEN)
            val people = vkResponse.response

            LoadResult.Page(
                data = people,
                prevKey = if (position == VK_STARTING_PAGE_INDEX) null else position - 1,
                nextKey = if (people.isEmpty()) null else position + 1
            )
        } catch (exception: IOException) {
            LoadResult.Error(exception)
        } catch (exception: HttpException) {
            LoadResult.Error(exception)
        }
