Na minha aplicação eu quero usar Retrofit para obter alguns dados do servido
Eu escrevo códigos abaixo, mas quando executar o aplicativo e chamar a API, mostre-me abaixoerror:

E/socketLogResponse: Err : com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $

Por favor, veja meus códigos acima e me ajude

esposta @API do servidor:

{
    "status": "ok",
    "time": 0.014972925186157227
}

nterface @ApiService:

@POST("api/log")
    Call<SocketPingResponse> getSocketPingLog(@Header("jwt") String jwt, @Body SocketPingBodySendData socketPingBodySendData);

lasse @SocketPingResponse:

public class SocketPingResponse {
    @SerializedName("status")
    @Expose
    private String status;
    @SerializedName("time")
    @Expose
    private Double time;

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public Double getTime() {
        return time;
    }

    public void setTime(Double ,time) {
        this.time = time;
    }
}

lasse @SocketPingBodySendData:

public class SocketPingBodySendData {
    @SerializedName("auction_id")
    @Expose
    int auction_id;
    @SerializedName("data")
    @Expose
    List<SocketPingEntity> data;

    public int getAuction_id() {
        return auction_id;
    }

    public void setAuction_id(int auction_id) {
        this.auction_id = auction_id;
    }

    public List<SocketPingEntity> getData() {
        return data;
    }

    public void setData(List<SocketPingEntity> data) {
        this.data = data;
    }
}

Códigos de chamada dapi em atividade:

pingEntityList.addAll(socketPingDatabase.socketPingDao().getSocketPingEntityList());
                        SocketPingBodySendData pingBodySendData = new SocketPingBodySendData();
                        pingBodySendData.setAuction_id(auctionID);
                        pingBodySendData.setData(pingEntityList);
                        Toast.makeText(context, ""+pingEntityList.size(), Toast.LENGTH_SHORT).show();
                        Call<SocketPingResponse> pingResponseCall = apis.getSocketPingLog(jwtToken, pingBodySendData);
                        pingResponseCall.enqueue(new Callback<SocketPingResponse>() {
                            @Override
                            public void onResponse(Call<SocketPingResponse> call, Response<SocketPingResponse> response) {
                                    if (response.body() != null) {
                                        Toast.makeText(context, response.body().getStatus(), Toast.LENGTH_SHORT).show();
                                        if (response.body().getStatus().equals("ok")) {
                                            pingEntityList.clear();
                                            socketPingDatabase.socketPingDao().deleteAll();
                                        }
                                    }
                            }

                            @Override
                            public void onFailure(Call<SocketPingResponse> call, Throwable t) {
                                Log.e("socketLogResponse", "Err : " + t.toString());
                            }
                        });

Como posso corrigir esse problema?
