问如何从分页源或远程中介库调用不同的api资源

@GET("/movie?min=20")

data class movie(
  var id: Int?,
  var name: String?,

@GET("/movie?count=20&&before={time}")

data class movie(

data class Genre(

Type mismatch.
Required:
List<TypeVariable(Value)>
Found:
ArrayDeque<Genre>?

package com.example.multirequestpaging

class DataSource {

    data class MovieResult(
        val result: ArrayDeque<Genre>?,
        val nextKey: String?
    )

    fun fetchInitialMovie(): MovieResult {
        val response = ApiInterface.create().getMovieResponse(20)

        return MovieResult(
            addInArrayDeque(response),
            response.items?.last()?.date
        )
    }

    fun fetchMovieBefore(key: String): MovieResult {
        val response = ApiInterface.create().getMovieResponseBefore(20, key)

        return MovieResult(
            addInArrayDeque(response),
            response.items?.last()?.date
        )
    }

    private fun addInArrayDeque(response: MovieResponse): ArrayDeque<Genre> {
        val result: ArrayDeque<Genre> = ArrayDeque()
        response.items?.forEach {
            result.add(it)
        }

        return result
    }
