How to catch the "Uncaught (in promise) Error..." when beforeEach return false

[zhaojjiang]

Some pages/routes requires redirect to sso/oauth to login, then we redirect away with location.href and return false in router.beforeEach guard to block render, however, there is always an Uncaught (in promise) Error: Navigation aborted from "/" to ..., how to catch this Uncaught? or what is the best practise for this scene?

This could be because in one of your guard you throw an Error and somewhere you do router.push() without a .catch(). Otherwise, aborted navigations no longer reject the navigation promise

thanks for your reply.

I tried a new project, debug and compare two projects, move / remove code, and finally found the error is thrown by router.isReady in my App.vue, append catch to it solved the uncaught!
