reactjs - React Promise不起作用

我正在调用一个动作创建者并将其发送到reducer并使用react promise来处理promise。但是我收到了一个错误，并且不确定如何修复它或在我的代码中查找。

this.props.loginUser(props)
.then(() => {
  console.log("success");
}).catch(error =>{
  console.log(error);
});

错误：

<body> tried to unmount. Because of cross-browser quirks it is impossible to unmount some top-level components (eg <html>, <head>, and <body>) reliably and efficiently. To fix this, have a single top-level component that never unmounts render these elements.

Mount React App：

ReactDOM.render(
  <Provider store={createStoreWithMiddleware(reducers)}>
    <Router history={browserHistory} routes={routes} />
  </Provider>
  , document.getElementById('app'));

的index.html

  <body>
    <div id="app"></div>
  </body>
