Riot coupled with Riot-route crashes on the latest version

[steevepay]

I tried to migrate to the latest version:

• Riot 7.1.0 to Riot 9.1.5
• @riotjs/route 8.0.2 to @riotjs/route 9.1.5
  However the routing crashes, and pages are replicated.

The Riot app tries to check if the route exists, if yes, it prints the component, otherwise it display a 404 component.

To reproduce the issue, I created a repository with the minimum of code, the error is on the branch riot_route_error (not on main):
https://github.com/steevepay/riot9-issue/tree/riot_route_error

Clone the repo and install NPM packages:

npm install

Then start vite:

npm run dev

Then visit the URL, then you will see the following error:

The error is thrown from the index.riot file, at the following line:

this.update({ showNotFound: !this.state.pages.some(p => match(path.pathname, toRegexp(p?.path))) })  

I originally found this expression on your Riot-SSR example, then I used it for two years in production with Riot 7.1.0. That's why now I'm trying to migrate :D
