Olá, fiz o primeiro módulo de java ee, no final eu tentei importar o projeto pronto e na hora de subir o servidor apareceu este erro. O que pode ser?

17:19:40,287 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "casadocodigo.war")]) - failure description: {
