Define an implementation for a new function into a multitenancy app extension on SAP CAP

Hi ,

I have some issue when I try to extend a multitenant application into SAP CAP when I try to implement a new function.

Is good to know that I am using @sap/cds-mtxs library.

I already have deployed a multitenant app that was activated from a subscriber subaccount.

Also I was able to build and activate an extension app that add two new fields for an entity. Code below:

extend Sales with { // 2 new fields.... 
x_priority : String enum {high; medium; low} default 'medium'; 
x_salesRegion : String(44);

Now I am trying to add a new function to the service and implement it

extend service CatalogService with { 
function x_func() returns String;

Function implementation:

const cds = require("@sap/cds");
module.exports = cds.service.impl(async function (service) { this.on("x_func",async(req)=>{ return "Hello!"; }); });

After activating the extension and test the function x_func() on the subscriber I receive the following error message


Not sure if is possible to implement a function into a extension app and how.

Guide that I followed is here:
