The expression return $default_commands; seems to be an array, but some of its elements' types (ConsoleHelpers\JiraCLI\C...Command\VersionsCommand) are incompatible with the return type of the parent method ConsoleHelpers\ConsoleKi...ion::getDefaultCommands of type array<Symfony\Component\...tion\CompletionCommand>.
                                                                                                                                                                                                                                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
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 new Author('Johannes');
    }
}

class BlogPost extends Post {
    public function getAuthor() {
        return '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.
