# AUR3272 ## Error Message `AUR3272: Root RouteContext is not set. Did you forget to register RouteConfiguration, or try to navigate before calling Aurelia.start()?` ## Description This error occurs when router navigation is attempted but the root `RouteContext` has not been established. The most common causes are: * Router configuration was not registered. * Navigation is attempted before `Aurelia.start()` completes. ## Solutions * Ensure `RouterConfiguration` is registered (for example via `Aurelia.register(...)`). * Only navigate after `await aurelia.start()`. ## Troubleshooting * Verify your `main.ts` (or equivalent) registers router configuration exactly once. * Check whether navigation is triggered during construction/binding before the app is started. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
