Pessoal, estou com um problema no método precoPara da classe Produto.java. Estou acessando normalmente a lista e detalhes do produto. E na página de detalhe seleciono o tipo de preço (Ebook, Impresso ou Combo) e clico para comprar. Nessa hora é gerado o seguinte erro.

... 75 moreFiz todos os teste e consegui identificar que o método precoPara recebe o parâmentro normalmente, mas não retorna nada (null).
public BigDecimal precoPara(TipoPreco tipoPreco) {
return precos.stream().filter(preco -> preco.getTipo().equals(tipoPreco)).findFirst().get().getPreco();
}Estou sem entender, pois meu código compila normalmente e não acusa nenhum erro na expressão lambda.
