 When using a regular `router-link`, **none of these failures will log an error**. However, if you are using `router.push` or `router.replace`, you might come across an _"Uncaught (in promise) Error"_ message followed by a more specific message in your console. This is part of the _Navigation Failures_ system in Vue Router and it is only available from version 3.2.0 onwards but existed for a long time before: through the two optional callbacks, `onComplete` and `onAbort` that can be passed to `router.push`. Since version 3.1.0, `router.push` and `router.replace` return a _Promise_ if no `onComplete`/`onAbort` callback is provided. This _Promise_ resolves instead of invoking `onComplete` and rejects instead of invoking `onAbort`.
