Laravel Nova在观察员中开火

Question

I'm trying to fire an action in an observer. It looks like this:

class ClientObserver
{
    /**
     * @param Client $client
     * @return mixed
     */
    public function created(Client $client)
    {
        $request = new ActionRequest();

        $action = app(HarvestClientCreate::class);

        $collection = Collection::wrap($client);

        return DispatchAction::forModels(
            $request, $action, 'handle', $collection
        );
    }
}

But this is not working! I get this error:

Call to a member function getKey() on null
/projects/crm-nova/vendor/laravel/nova/src/Actions/ActionEvent.php", line: 193

When I trace that down it goes wrong in ActionEvent.php:

'user_id' => $request->user()->getKey(),

But when I set the user manually on the request it's not working as wel.

What could be going wrong here?
