Start with the reproduction in src/app.json and inspect build-plugin-rax-app/lib/Loaders/RouteLoader.js around getComponentName at line 104. Run the web build with the two-route configuration, compare its route expectations with the miniapp configuration, and consider the issue done when the web build completes without this error while the miniapp routes remain valid.
