Fala pessoal, terminei o curso agora. Ao fazer o passo de inserir vários livros para passar do preço suportado (R$ 500), fui adicionar um livro com esse valor (em vez de ficar adicionando vários livros no carrinho) e percebi que não estou conseguindo adicionar um "sumário" aos novos livros. Tentei cadastrar sem sumário e passou numa boa. Quando adiciono sumário ele lança essa exception.
