Are you sure the usage of $memory->loadData('test') targeting Spiral\Boot\NullMemory::loadData() seems to always return null.
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check looks for function or method calls that always return null and whose
return value is used.


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

}

$a = new A();
if ($a->getObject()) {





The method getObject() can return nothing but null, so it makes no sense
to use the return value.


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