Child, segment route with child route by method not routing

The top router here works. /property is a Literal route that doesn't terminate and picks up on GET actions on the child route. Below that I have a segment route that, like its parent, doesn't terminate and picks up on GET actions on the child route. It should respond to GET requests only on /property/12

I get a not-found error when routing there.

                ),

Your array is invalid. 'may_terminate' is not supposed to be inside 'options'. Not sure if this is causing all your issues, but try to update and see if it is solved:

            'by_id' => array(
                'type' => 'segment',
                'options' => array(
                    'route' => '/[:propertyId]'
                ),
                'may_terminate' => false,
                'child_routes' => array(
                    'get_by_id' => array(
                        'type' => 'method',
                        'options' => array(
                            'verb' => 'GET',
                            'defaults' => array(
                                'controller' => 'Property\Controller\Rest',
                                'action' => 'getById'
                            )
                        )
                    )
                )
            ),
