- Issue created by @R_H-L
On Drupal 11.1.1, when attempting to import a feed using the Feeds module, Tracer API throws a TypeError:
```
Message TypeError: Drupal\tracer\EventDispatcher\TraceableEventDispatcher::addCalledListener(): Argument #1 ($callable) must be of type array, Closure given, called in /opt/drupal/web/modules/contrib/tracer/src/EventDispatcher/TraceableEventDispatcher.php on line 158 in Drupal\tracer\EventDispatcher\TraceableEventDispatcher->addCalledListener() (line 172 of /opt/drupal/web/modules/contrib/tracer/src/EventDispatcher/TraceableEventDispatcher.php).
```
Import works correctly without Tracer.
Full Trace:
