Incrementing table id +1 with .save()

Hello everyone,

I used the solution on this page to insert a data on the specific table:

https://experienceleaguecommunities.adobe.com/t5/adobe-campaign-classic-questions/how-to-get-an-id-of-a-newly-inserted-recipient-in-javascript/m-p/322274

But when I add a data from this query, the id generated is spaced as 30 value.

On the table I was added pksequence sql (pkSequence="deliveryRichSmsId") which allows you to increment the id to +1. (the sql was executed) : 

SELECT CreateSequenceIfNecessary('deliveryRichSmsId', '1000', 'cache 1');

var result = sqlExec("INSERT INTO RenDeliveryRichSms (iDeliveryRichSmsId) VALUES (nextval('deliveryRichSmsId'))");

With sqlExec() the value set up to +1
but I need to use the solution with ".save()" function to get the id generated.

=> The .save() spaces the id by +30 on each insertion.

Do you know if there is a solution to this?

Best regards,

Ali
