Serenity Cucumber4 Environment URL on Page Objects not working

Question

Why does this not work?

When I run the feature file as "Run as Cucumber Feature" I get an error

java.lang.AssertionError: Undefined default URL for page object PageObject

Page Object

@DefaultUrl("page:register.page")
public class AccountCreationPage extends PageObject {
   ...
}

Config File (serenity.config)

environments {
  local {
    webdriver.base.url = "https://localhost"
  }
  demo {
    webdriver.base.url = "https://demo.example.com"
  }
  prod {
    webdriver.base.url = "https://example.com"
  }
  all {
    home.page = "#{webdriver.base.url}"
    register.page = "#{webdriver.base.url}/register"
  }
}

https://johnfergusonsmart.com/environment-specific-configuration-in-serenity-bdd/ shows the use of @DefaultUrl("page:register.page")

Answer 1

the config file is required to have default as an entry 🤦

environments {
  default {
    webdriver.base.url = "https://localhost"
  }
  ...
  all {
    home.page = "#{webdriver.base.url}"
    register.page = "#{webdriver.base.url}/register"
  }
}
