Bug introduced by
The property uri does not exist. Did you maybe forget to declare it?

In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code:

class MyClass { }

$x = new MyClass();
$x->foo = true;

Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion:

class MyClass {
    public $foo;
}

$x = new MyClass();
$x->foo = true;

Bug Best Practice introduced by
The return type of return \Redirect::to($this->redirectUri); (Illuminate\Http\RedirectResponse) is incompatible with the return type documented by Cellcote\LaravelProxify\Proxy::makeRequest of type Illuminate\Http\Response.

If you return a value from a function or method, it should be a sub-type of the type that is given by the parent type f.e. an interface, or abstract method. This is more formally defined by the Lizkov substitution principle, and guarantees that classes that depend on the parent type can use any instance of a child type interchangably. This principle also belongs to the SOLID principles for object oriented design.

Let’s take a look at an example:

class Author {
    private $name;

    public function __construct($name) {
        $this->name = $name;
    }

    public function getName() {
        return $this->name;
    }
}

abstract class Post {
    public function getAuthor() {
        return 'Johannes';
    }
}

class BlogPost extends Post {
    public function getAuthor() {
        return new Author('Johannes');
    }
}

class ForumPost extends Post { /* ... */ }

function my_function(Post $post) {
    echo strtoupper($post->getAuthor());
}

Our function my_function expects a Post object, and outputs the author of the post. The base class Post returns a simple string and outputting a simple string will work just fine. However, the child class BlogPost which is a sub-type of Post instead decided to return an object, and is therefore violating the SOLID principles. If a BlogPost were passed to my_function, PHP would not complain, but ultimately fail when executing the strtoupper call in its body.

Bug introduced by
Are you sure the assignment to $grantType is correct as \Cellcote\LaravelProxify...y\ProxyAux::GRANT_TYPE) (which targets Cellcote\LaravelProxify\ProxyAux::getQueryValue()) seems to always return null.

This check looks for function or method calls that always return null and whose return value is assigned to a variable.

class A
{
    function getObject()
    {
        return null;
    }

}

$a = new A();
$object = $a->getObject();

The method getObject() can return nothing but null, so it makes no sense to assign that value to a variable.

The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes.
