Deprecated Code introduced by
The property Chubbyphp\Serialization\...ContextBuilder::$groups has been deprecated.

This property has been deprecated. The supplier of the class has supplied an explanatory message.

The explanatory message should give you some clue as to whether and when the property will be removed from the class and what other property to use instead.

Bug Best Practice introduced by
The return type of return $this; (Chubbyphp\Serialization\...ormalizerContextBuilder) is incompatible with the return type declared by the interface Chubbyphp\Serialization\...derInterface::setGroups of type self.

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.
