Angularjs sfSmartsync（）.syncUp函数提供成功，但未反映在Salesforce服务器上的更改中

我正在尝试使用以下方法在sendbox帐户上为Salesforce中的脱机设备实现同步功能：

var sfSmartsync = function() {
            return cordova.require("com.salesforce.plugin.smartsync");
        };
        target = {
        };

        /*target = {
         type : "Lead"
         query : "select * from {Lead}"
         };*/

        options = {
            mergeMode : sfSmartsync().MERGE_MODE.OVERWRITE,
            attributes: {type:"Lead"}
        };
        soupName = "Lead";
        // sfSmartsync().syncUp(false, target, soupName, options, function sucessCallback(params) {
        sfSmartsync().syncUp(soupName, options, function sucessCallback(params) {
            alert("Sync Up Sucess");
            console.log(JSON.stringify(params));

        }, function errorCallback() {
            alert("Sync Up Error");

        });

我获得了一个成功，那就是：

{"status":"NEW","target":{"modificationDateFieldName":"LastModifiedDate","idFieldName":"Id","type":"rest"},"_soupEntryId":3,"maxTimeStamp":0,"totalSize":-1,"type":"syncUp","progress":0,"options":{"mergeMode":"OVERWRITE"},"soupName":"Lead"}

但是当我回到Salesforce服务器时，我在数据库中找不到我的更改。如果有人做了那样的事，请帮帮我
