RESUMO

Isso pode não ser um bug, mas apenas algo que consegui em versões mais antigas, mas com Ansible 2.3 RC1 se estou verificando se uma variável registrada por um módulo (com uma cláusula when) está definida e, em seguida, obter um valor de subdict que irá falhar em 2.3 enquanto em 2.2 e abaixo funciona bem. Isso acontece especificamente quando o módulo que registra a variável é ignorado por qualquer motivo e, em seguida, uma tarefa subsequente verifica se a variável está definida e, em seguida, obtém a subchave.
