router-plugin versions 1.150.0 and later generate routeTree.gen.ts with type declaration errors

[faner11]

Which project does this relate to?

Router

Describe the bug

The routeTree.gen.ts generated in versions after @tanstack/router-plugin 1.150.0 is inconsistent with version 1.150.0. I created a test path, and the following code was normal in version 1.150.0, passed the TypeScript check, but in subsequent versions, this code still works normally, but the TypeScript check reports an error.

  const router = useRouter();
  React.useEffect(() => {
    console.log(router.routesByPath['/test']);
  }, [router]);
