Estou lendo a apostila do curso FJ28 da Caelum, e não consegui realizar o Execício 11.6 do Item 12.
Se alguém poder me ajudar a solucionar este erro, segue abaixo as infomação que acho necessário para que os interessados possam me ajudar.

}
[b]@Get

result.use(json()).withoutRoot()
.from(dao.busca(q))
.exclude("id", "descricao")
