        .addConverterFactory(GsonConverterFactory.create())
        .client(client)
        .build()

    fun<T> buildService(service: Class<T>): T{
        Security.insertProviderAt(Conscrypt.newProvider(), 1);
        return retrofit.create(service)
    }
}

LinesrsEndpoint.kt

interface LinesrsEndpoint{
    @GET("/getAllLinesrs")
    fun getLinesrs(): Call<AllLinesrs>
}

data class AllLinesrs(val results:List<Linesrs>)

data class Linesrs(
    var lineId: Int,
    var symbolId: String,
    var lineStart: String,
    var lineEnd: String,

        val request = ServiceBuilder.buildService(LinesrsEndpoint::class.java)
        val call = request.getLinesrs()

        call.enqueue(object : Callback<AllLinesrs> {
            override fun onResponse(call: Call<AllLinesrs>, response: Response<AllLinesrs>) {
                if (response.isSuccessful) {
                    Log.e("hamid", "onResponse: "+response.body() )

            }

            override fun onFailure(call: Call<AllLinesrs>, t: Throwable) {
