PHP 8: Error Unknown named parameter

Since Updated PHP to 8 I'm getting this error: Error Unknown named parameter $campaign

And point the error to this line:

public function callAction($method, $parameters)
{
	//This line error
	return call_user_func_array([$this, $method], $parameters);

}

This is my route:

Route::get('/campaign_sent/{campaing}', 'CampaignsController@sentView')
    ->where('campaign', '[0-9]+')
    ->middleware('auth');

And my Controller:

public function sentView(Campaign $campaignData)
{
	return view('emailcampaign.sent_view');
}

Everything was working great just before the update.
