Query->paginate not compatible with Eloquent

[pildit]

I installed the package in my Lumen app ("laravel/lumen-framework": "5.4.*").

I got an error when i'm using the paginate method of the Query class.
As you can see, the signature of the paginate method
public function paginate($per_page = 10, $page_name = "page", $page = null)
is not compatible with the one found in \vendor\illuminate\database\Eloquent\Builder.php

public function paginate($perPage = null, $columns = ['*'], $pageName = 'page', $page = null)
Eloquent/Builder.php

so I had to modify the Model class in order to re-arrange correctly the parameters for paginate.

Is this a bug ??
