如何在相同的化简器中持久化嵌套对象？

Question

我正在使用redux-persist，并且将对象嵌套在如下所示的reducer中

const initState = {
    ian: "initial value",
    details: {
        prop1: "inital value",
        prop2: "inital value"
    }
};

// Reducer (SomeReducer) create

const persistcnfg = {
    key: "SomeReducer",
    storage: storage
},

const rootReducer = combineReducers({
    someReducer: persistReducer(persistcnfg, SomeReducer)
});

我可以看到更改保存了localstorgae，但是当重新加载页面时 值更新为1，但是details值重置为intialState。 我如何也可以持久保留嵌套对象。
