Olá pessoal!
Estou tendo um probleminha na minha aplicação web spring boot com angular.
Ao tentar salvar um formulário estou tendo essa mensagem de erro:
Parece que a API java está esperando um ArrayList ([]), e vc está enviando uma String vazia.
Entendi. Já meche em tudo aqui para tentar descobrir mais não tive êxodo.
Esse problema apareceu quando fiz as relações da entidades. Você acha que tem alguma relação?
Posta como vc está fazendo a requisição do frontend, e como está o método do endpoint que está sendo chamado no backend.
Só um momento.
No console do navegador, como está o body da requisição?
Quando for postar código, evite sempre que puder, enviar imagens do código. É bem melhor copiar e colá-lo na postagem. Fica melhor de entender.
Entendi.
No console do navegador:

O que tem nessa linha: profissional-create.component.ts:100:34? E o body da requisição que vc pega na aba network do console do navegador:
profissional-create.component.ts:100:34 ?
} else if (err.error.errors[0].message === “número do registro de contribuinte individual brasileiro (CPF) inválido”) {
this.service.message(“CPF inválido!”)
console.log(err)
}
body da requisição:
-
{id: “”, nome: “Dhonata Borges de Oliveira”, nascimento: “2022-02-15T03:00:00.000Z”, sexo: “masculino”,…}
-
cargos: “cado.id”
-
cpf: “133.120.446-18”
-
disciplinas: “”
-
id: “”
-
nascimento: “2022-02-15T03:00:00.000Z”
-
nome: “Dhonata Borges de Oliveira”
-
rg: “mg19599000”
-
sexo: “masculino”
-
telefone: “38998736845”
-
turmas: “”
Pelo erro, parece que nessa parte:
err.error.errors[0]
provavelmente o array errors está undefined. Tem certeza que o response da requisição está nessa estrutura? (vc consegue ver o retorno do backend na aba network do console do navegador)
Vou tentar.

Seria esse?
Não foi esse que pedi, mas serve.
O problema é que vc está passando a propriedade disciplinas como string vazia (''). E está tentando receber essa string vazia na classe Disciplina. Essa conversão não é possível. Ou vc passa um os dados corretos da disciplina em um array, ou passa um array vazio ([]).
A propriedade prof do componente ProfissionalCreateComponent, possui uma outra propriedade chamada disciplina sendo inicializada com uma string vazia: ''. Em vez disso, tente passar uma array vazio:
disciplinas: [],
Entendi, essa disciplina esta relacionada com a classe profissional com anotação @ManyToMany. Isso pode interferir no front?
O problema é a forma como as disciplinas estão sendo enviadas do front para o back. Se as disciplinas são um array no back, como que elas estão sendo passadas como string pelo front?
