 To access the complete errors, including their stack, you can register an event listener:
 
 ```js
-  server.events.on({ name: 'request', channels: 'internal' }, (request, event, tags) => {
-    if (tags.auth && tags.error) {
-      console.log(event.error);
-    }
-  });
+server.events.on({ name: 'request', channels: 'internal' }, (request, event, tags) => {
+  if (tags.auth && tags.error) {
+    console.log(event.error);
+  }
+});
 ```
 
 In this, debugging `hapi-auth-any` isn't different from debugging other strategies. However, in order to preserve the errors that caused `hapi-auth-any` to fail, it throws an [AggregateError](https://github.com/sindresorhus/aggregate-error), decorated with some [boom](https://github.com/hapijs/boom)-specific properties. `AggregateErrors` are iterable, which is how you can access the individual errors.
