Bug introduced by
The property channelManager 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 introduced by
Accessing app on the interface Ratchet\ConnectionInterface suggest that you code against a concrete implementation. How about adding an instanceof check?

If you access a property on an interface, you most likely code against a concrete implementation of the interface.

Available Fixes

  1. Adding an additional type check:

    interface SomeInterface { }
    class SomeClass implements SomeInterface {
        public $a;
    }
    
    function someFunction(SomeInterface $object) {
        if ($object instanceof SomeClass) {
            $a = $object->a;
        }
    }
    
  2. Changing the type hint:

    interface SomeInterface { }
    class SomeClass implements SomeInterface {
        public $a;
    }
    
    function someFunction(SomeClass $object) {
        $a = $object->a;
    }
