Hello Pooja,

Welcome to Outsystems Community,

This error occur when we try to save an Entity record with a NullIdentifier() as key.
Please check in your action flow where you are passing Null identifier for your Entity's attribute (Id),

Thanks & Regards

I think you should check is there any Update{Entity} in your actions and make sure the Id is not 0 (OR nullIdentifier()).

Here is possible similar issue [].dbo.[] with key 0 was not updated | OutSystems .

Hope this helps,
