Problem to update data

Good morning friends, I'm about 3 days with difficulties in an error that has been occurring in my application.

I have two entities, CLIENT and VEI. I did the mapping bidirectionally saying that my client may have one or more vehicles.

private List<Veiculo> veiculo = new ArrayList<>();

@OneToMany(mappedBy = "cliente", cascade= CascadeType.ALL, fetch = FetchType.LAZY)
public List<Veiculo> getVeiculo() {
    return veiculo;}

I can register the Customer and the vehicle related to it normally. But I can not edit them. I created a screen where I search the client. WhenIclicktheeditbutton,ittakesthevalueoftheidtodotheconversionandsetsthedataalreadyfilledintotheclienteditscreen.Allvaluesarefilledastheynormallyshould,butwhenattemptingtosavetheclientobjectafterachangehasbeenmade.Ihavethefollowingerror.
