'managed' aspect adding createdBy_user, modifiedBy_user columns in SAP CAPM framework

Hello .

I have a simple CDS structure like below.

namespace com.atom.app; 
using {managed ,Currency , temporal } from '@sap/cds/common'; 
entity Product { 
key productId   : Integer; 
productType : Integer; 
name        : String(30); 
description : String(100); 
basePrice   : Decimal(10, 3); 
currency    : Currency ; 
ItsProductType : Association to one ProductType on ItsProductType.productTypeId = $self.productType; 
}; 

entity ProductType : managed { 
key productTypeId : Integer; 
name          : String(20); 
description   : String(100); 
ItsProducts   : Association to many Product on ItsProducts.productType = $self.productTypeId;
 };

if you look at the ProductType entity , I am using managed aspect. I am deploying this structure to HANA Express edition XSA ( virtual machine ). Corresponding hdbcds has the below fields

using COM_ATOM_APP_PRODUCT as COM_ATOM_APP_PRODUCT;
entity COM_ATOM_APP_PRODUCTTYPE {
  CREATEDAT : UTCTimestamp;
  CREATEDBY : String(255);
  MODIFIEDAT : UTCTimestamp;
  MODIFIEDBY : String(255);
  key PRODUCTTYPEID : Integer;
  NAME : String(20);
  DESCRIPTION : String(100);
  ITSPRODUCTS : association[*] to COM_ATOM_APP_PRODUCT on ITSPRODUCTS.PRODUCTTYPE = PRODUCTTYPEID;
};

But, when I am trying to post a record against this entity set , it throws an error message saying " "message": "invalid column name: CREATEDBY_USER"

Backend logs :

ERR query: 'INSERT INTO com_atom_app_ProductType ( productTypeId, name, description, createdAt, createdBy_user, modifiedAt, modifiedBy_user, createdBy, modifiedBy ) VALUES ( ?, ?, ?, ?, ?, ?, ?, ?, ? )

Why is the framework expecting the table to have createdBy_user & modifiedBy_user ? Is it anything to do with the version of npm packages I am using ?

error is thrown from my VS code ( when I run CDS watch ) and from XSA as well after deployment.

attached mta.yaml and package.json of my CDS project

gregorwolf great help of you could look at it.

The column name is CREATEDBY not createdBy_user.

[sreehari_vpillai]

It must have been. But , not sure why , the framework expected createdBy_user.

this was the error I got.

ERR query: 'INSERT INTO com_atom_app_ProductType ( productTypeId, name, description, createdAt, createdBy_user, modifiedAt, modifiedBy_user, createdBy, modifiedBy ) VALUES ( ?, ?, ?, ?, ?, ?, ?, ?, ? )

anyway , after re pushing certain more changes , this issue doesnt show up any more ( tbh I don't know what fixed it )
