The validate returns an error object. How do I get the correct field name and the corresponding check message about protovalidate-go HOT 2 CLOSED

// A ValidationError is returned if one or more constraints on a message are
// violated. This error type can be converted into a validate.Violations
// message via ToProto.
//
//    err = validator.Validate(msg)
//    var valErr *ValidationError
//    if ok := errors.As(err, &valErr); ok {
//      pb := valErr.ToProto()
//      // ...
//    }
ValidationError = errors.ValidationError
