使用iView.Spin.show();报错

部分源码：
function apiAxios(method, url, params, config) {
**iView.Spin.show()**
axios({
method: method,
url: url,
data: params,
withCredentials: false
}).then((res) => {
**iView.Spin.hide()**
}).catch((err) => {
**iView.Spin.hide()**
errorHandler(err, config.errorFn)
})
}

报错：
Uncaught TypeError: Failed to execute 'removeChild' on 'Node': parameter 1 is not of type 'Node'

Start with the apiAxios snippet in the issue and reproduce the browser error around iView.Spin.show() and iView.Spin.hide(). Inspect the generated project and the browser console to determine which call triggers the removeChild failure. Done means the request flow can show and hide the spinner without the reported Node error.
