routeDiscovery is undefined even explicitly specified

[yf-yang]

Reproduction: https://github.com/yf-yang/rsbuild-react-router-bug (This is just a copy of the default-template, with all packages updated to latest)

To reproduce:

pnpm i
pnpm dev
// open localhost:3000 and got an internal error

error message: TypeError: Cannot read properties of undefined (reading 'manifestPath')

That's because RR7.6 introduced a new config routeDiscovery. However, I cannot easily figure out what's the package that triggers the issue. Simply bumping RR to 7.6 and rsbuild/core to latest (1.3.18) cannot trigger the error.

react-router.config.ts:

import type { Config } from "@react-router/dev/config";

export default {
  // Config options...
  // Server-side render by default, to enable SPA mode set this to `false`
  ssr: true,
  routeDiscovery: { mode: "initial" },
} satisfies Config;

somehow you can revert the version of RR to 7.1.3 and it works. and using vite version 5

@dionfananie Thx, actually I am staying with 7.5.3, but it would be definitely good if the bug got fixed :)

Hey @dionfananie, I change the RR version to be 7.1.3 and I still got the same error, and I try to clone yours https://github.com/dionfananie/react-router-rsbuild, also got the same error

@ScriptedAlchemy @chenjiahan Sorry to bother, would you mind taking a look somehow?
