Lumen - Class url does not exist - php

Question

I am using Lumen to create a website, and while my controllers, routes, and views are well configured, I get an error when I try to use the redirect function in a controller.
This is the error code :
ReflectionException in Container.php line 736: Class url does not exist
in Container.php line 736

My route is well recognized, (you can see it transformed as it should in the error).
Here is the code that I use in my controller :
public function unarchive($attribute){
Token::query()->find($attribute)->update(['is_archived'=>0]);
return redirect(route('token.archived'));
}
I also uncommented the following from boostrap/app.php :
$app->withFacades();
$app->withEloquent();
Is there a problem using the function redirect() with Lumen ? I tried both redirect(route()) and redirect()->route(), and they gave the same result.

If you are on 5.2 there is an issue open for this.
Lumen - Github Issues - redirect() doesn't work, Lumen 5.2 #315
You can use the Illuminate\Http\RedirectResponse directly if needed. (from workaround link below):
return new RedirectResponse('login');
return RedirectResponse::create('login');
Possible workaround from Github Issue
