SSR request raises error 500 after upgrade to vue-router 3.3.0 on beforeEach redirection

[dmitry]

Running on SSR if you have router.beforeEach in boot and it redirects via next({name: 'path'}) anywhere, with new vue-router since v3.3.0 it will raise error on the server. It happens because with this release of vue-router special error are thrown: vuejs/vue-router#3047

To prevent from this issue catch should be added to the router.push(url) in the server-entry.js.

router.push(url).catch(() => {})

Probably it should be solved somehow without even catching errors at all, but for now I know the only one way how to solve that. As this file is generated automatically and it has comments

There are no real solution to that issue, except rollback to vue-router v3.2.0.

quasar/app: 1.9.5
mode: ssr
vue-router: 3.3.2

This also means that your route is not correct.
Would you be so kind to offer a barebones reproduction repo of your issue?

@rstoenescu thank you for the quick response!

Here is a git repo with reproduction of this issue:
https://github.com/dmitry/quasar-route3-3-repro

If you go to the /auth (http://localhost:8080/auth) path, it will not work and results in 404 with:

UnhandledPromiseRejectionWarning: Error: Redirected from "/" to "/auth" via a navigation guard.

If you try the same on the client you will see it works, it just redirects to root URI.

This sure seems like something that's been missed on the design of the new errors in regards to SSR. Hope I'll have some bandwith to report this issue to vue-router. Their docs should get updated, including the SSR example on ssr.vuejs.org.

Meanwhile, the catch() block should be there regardless of vue-router 3.2 or 3.3. So added it for "@quasar/app" v1.9.6 -- and also temporarily downgraded vue-router to 3.2 cause on 3.3 even if we catch the error, the router.onReady hook does not matches any components and so it generates a 404 error anyway.
