Error get lastInsertId in Try catch

Hi, I have a problem getting the last id of a related table. if I use $ variation-> id; it brings me null and if I use $ variation-> theInsertId (); I get an error with foreign key problems

Can you get the last id after a save in a try catch?

<?php try{ ///////Iniciar bloque de transacción///////////////////////// $this->db->begin(); if (count($prev_month_balance) > 0) {

                $variation =  new VariationsLastMonth();

                $variation->setMonthPrev($prev_month_balance[0]->getRate());
                $variation->setMonthCurrent($rate_);
                $variation->setYear(date("Y"));
                $variation->setState(1);

                if ($variation->save()){
                    $lastId = $variation->id(); 
                }else{
                    throw new Exception("¡ERROR: al inserta en la bd!", 1);
                }

            }

            $month_current = date("m");
            $year_current = date("Y");
            $detailBalance = DetailsBalance::query()
                ->where("id_bank = :id_bank:")
                ->andWhere("id_sub_product = :id_sub_product:")
                ->andWhere("id_concept = :id_concept:")
                ->andWhere("year = :year:")
                ->andWhere("id_month = :month:")
                ->bind(["id_bank" => $id_bank, "id_sub_product" => $id_sub_product, "id_concept" => $id_concept, "month" => $month_current, "year" => $year_current])
                ->execute();

            if (count($detailBalance) > 0) {
                // Validamos si existe el sub producto + banco + registrado
                $this->response->setJsonContent(array(
                    "subProduct_repeat" => true
                ));
                return $this->response->send(); // aqui se envia la respuesta ajax de nuevo a la vista
            }

            $rate =  new DetailsBalance();

            $rate->setIdBank(intval($id_bank));
            $rate->setIdSubProduct(intval($id_sub_product));
            $rate->setIdConcept(intval($id_concept));
            $rate->setRate($rate_);
            $rate->setYear(intval(date("Y")));
            $rate->setIdMonth(intval(date("m")));
            $rate->setIdVariationLastMonth($lastId);
            $rate->setState(1);

            //mostrando mensajes de error de insercion en bd
            if (!$rate->save()){
                throw new Exception("¡ERROR: al inserta en la bd!", 2);
            }

            ///////Finalizar bloque de transacción y guardar/////////////
            $this->db->commit();
        }catch(\Exception $e){

            ///////Deshacer cambios hechos en el/////////
            ///////bloque de transaccion respestivo//////
            $this->db->rollback();
            $this->response->setJsonContent(array(
                "error_registro" => $e->getMessage()
            ));

            $this->response->setStatusCode(200, "OK"); //la peticion ha sido realizada con exito
            return $this->response->send(); // aqui se envia la respuesta ajax de nuevo a la vista

        }

You have method id() here. It should just property. Also you should in your database have column id with PRIMARY key?

If Mr. the table has an id as a primary key, it is called id_variation_last_month. this is the model

<?php

class VariationsLastMonth extends \Phalcon\Mvc\Model {

/**
 *
 * @var integer
 * @Primary
 * @Identity
 * @Column(type="integer", length=11, nullable=false)
 */
protected $id_variation_last_month;

/**
 * Method to set the value of field id_variation_last_month
 *
 * @param integer $id_variation_last_month
 * @return $this
 */
public function setIdVariationLastMonth($id_variation_last_month)
{
    $this->id_variation_last_month = $id_variation_last_month;

    return $this;
}

/**
 * Returns the value of field id_variation_last_month
 *
 * @return integer
 */
public function getIdVariationLastMonth()
{
    return $this->id_variation_last_month;
}

/**
 * Initialize method for model.
 */
public function initialize()
{
    $this->setSchema("sieg");
    $this->setSource("variations_last_month");
    $this->hasMany('id_variation_last_month', 'DetailsBalance', 'id_variation_last_month', ['alias' => 'DetailsBalance']);
}

Then you need to use getIdVariationLastMonth() method.
