How do you extend a deploymentNode?

[caligo-mentis]

Description

We are trying to model complex enterprise landscape using c4 according to the enterprise modelling example, everything works fine except deployment diagrams. When trying to extend deploymentNode the following error occurs:

workspace.dsl: An element/relationship identified by "dataCenter" could not be found

Steps to reproduce

1. Define some deploymentEnvironment and deploymentNode in system-catalog.dsl
2. Try to !extend deploymentNode from system-catalog in software system workspace

        orderService = softwareSystem "Order Service"
        invoiceService = softwareSystem "Invoice Service"
        customerService = softwareSystem "Customer Service"

        live = deploymentEnvironment "Live" {
            dataCenter = deploymentNode "Data Center"
        }

    views {
        styles {
            element "Person" {
                shape person
