Patch logic maybe not work for the message that contains a enum?

func DefaultReadLimiter(ctx context.Context, in *Limiter, db *gorm.DB) (*Limiter, error) {
	if in == nil {

	}
	ormObj, err := in.ToORM(ctx)
	if err != nil {

	if ormObj.Id == 0 {
		return nil, errors.EmptyIdError
	}
	if hook, ok := interface{}(&ormObj).(LimiterORMWithBeforeReadApplyQuery); ok {
		if db, err = hook.BeforeReadApplyQuery(ctx, db); err != nil {
			return nil, err
		}
	}
	if db, err = gorm1.ApplyFieldSelection(ctx, db, nil, &LimiterORM{}); err != nil {
		return nil, err
	}
	if hook, ok := interface{}(&ormObj).(LimiterORMWithBeforeReadFind); ok {
		if db, err = hook.BeforeReadFind(ctx, db); err != nil {
			return nil, err
		}
	}
	ormResponse := LimiterORM{}
	if err = db.Where(&ormObj).First(&ormResponse).Error; err != nil {
		return nil, err
	}

DefaultPatch call the DefaultRead, and DefaultRead use the returns from ToORM as where condition, and the ToORM logic is: enum value must have a value. eg:

func (m *Limiter) ToORM(ctx context.Context) (LimiterORM, error) {
	to := LimiterORM{}
	var err error
	if prehook, ok := interface{}(m).(LimiterWithBeforeToORM); ok {
		if err = prehook.BeforeToORM(ctx, &to); err != nil {
			return to, err
		}
	}
	to.Id = m.Id
	to.MatchMode = m.MatchMode
	to.MatchValue = m.MatchValue
	to.Query = m.Query
	to.Headers = m.Headers
	to.LimitQps = m.LimitQps
	to.Alias = m.Alias
	to.ClusterIdentifier = m.ClusterIdentifier
	to.Status = Status_name[int32(m.Status)]

finnaly, the sql is SELECT * FROMlimiters WHERE (limiters.id = 3) AND (limiters.status= 'STATUS_UNSPECIFIED') ORDER BYlimiters.id ASC LIMIT 1.

the result is err: record not found

How to patch?
