[Framework7 v3] Catch Router Error

How can i catch the router error.
I have use routerAjaxError, but when the router request success and cached, it will not work.
I read the Framework7 Source found that next the reject function it will throw the error. How can i catch it or How can i custom the reject function.

You can’t catch this error, routerAjaxError should work fine and give you an option to handle it, but this error will anyway appear

If i disable xhrCache, routerAjaxError triggers every time. But when xhrCache is enable, it is triggered only at the first request.

The test scenario : request again after network interruption.
