Zend Framework 2 segment route required segment

I am trying to make a route (or two) that will let me invoke two different actions with the below URL formats.

mydomain.com/profile
mydomain.com/profile/1234/something

For the second format, the 1234 should be a required integer value, while something should be an optional string. The first format is simple by using a literal route. I thought I could add a segment child route for the second format, but I cannot get it to work. I tried to leave out the first format and only do the second one with a segment route, but I wasn't successful in that either.

Here is what I tried:

'profile' => array(
    'type' => 'Zend\Mvc\Router\Http\Literal',
    'options' => array(
        'route' => '/profile',
        'defaults' => array(
            'controller' => 'User\Controller\User',
            'action' => 'profile'
        )
    ),
    'child_routes' => array(
        'profile_view' => array(
            'type' => 'Zend\Mvc\Router\Http\Segment',
            'options' => array(
                'route' => '/:code[/:username]',
                'constraints' => array(
                    'code' => '[0-9]*',
                    'username' => '[a-zA-Z0-9_-]*'
                ),
                'defaults' => array(
                    'controller' => 'User\Controller\User',
                    'action' => 'view_profile'
                )
            )
        )
    )
)

For mydomain.com/profile, I get the following errror:

Fatal error: Uncaught exception 'Zend\View\Exception\RuntimeException' with message 'No RouteMatch instance provided'

For mydomain.com/1234/something, I get the following error:

Fatal error: Uncaught exception 'Zend\Mvc\Router\Exception\InvalidArgumentException' with message 'Missing parameter "code"'

The manual states the following:

If a segment is optional, it should be surrounded by brackets. As an example, “/:foo[/:bar]” would match a “/” followed by text and assign it to the key “foo”; if any additional “/” characters are found, any text following the last one will be assigned to the key “bar”.

Is that not exactly what I am doing? The above errors remain the same if I comment out the constraints.

What am I missing here? Thanks in advance.

My solution: Set the default for your optional parameter to empty string

I ran into a similar problem, I solved it by setting the default value for the optional parameter (in your case "username" to an empty string ""; My solution:

'users' => array(
    'type' => 'segment',
    'options' => array(
        'route' => '/users[/:user_id]',
        'constraints' => array(
            'user_id' => '[0-9]*',
        ),
        'defaults' => array(
            'controller' => 'My\Controller\User',
            'user_id' => ""
        )
    ),
