使用Amplify自定义GraphQL查询时无法获取nextToken求助

// MovieList 函数定义
private fun getMovieList(): GraphQLRequest<MovieDBFinal2> {
    val document = ("query getMovieList { "
            + "listMovieDBFinal2s(limit: 1000, filter: {Genre1: {eq: \"Animation\"}}) { "
            + "nextToken "
            + "items { "
            + "IMDB_title "
            + "} "
            + "} "
            + "} ")

    return SimpleGraphQLRequest(
        document,
        Collections.emptyMap(),
        TypeMaker.getParameterizedType(QueryResponse::class.java, MovieDBFinal2::class.java),
        GsonVariablesSerializer())
}

internal class QueryResponse<T> {
    private val listMovieDBFinal2s: QueryList<T>? = null

    val moviesList: QueryList<T>?
        get() = listMovieDBFinal2s
}

internal class QueryList<T> {
    val items: Iterable<T>? = null
    val nextToken: String? = null
}


// MovieList 函数调用
Amplify.API.query(
    getMovieList(),
    { response ->
        if (response.hasData()) {
            Log.e("MovieList", "$response")
        }

    },
    { failure ->
        Log.e("MovieList", "Query failed.", failure)
    }
)

• 在Schema中使用自定义类型无效
• PaginationResult无法正常工作，Iterable无法返回nextToken
• 仅能以String.class类型完成请求，但后续序列化难度大
• 当前临时解决方案：发起两次相同请求，一次传入nextToken使用PaginationResult，另一次使用String.class类型
