Upgrade error on OCC extension with JS Storefront 404 not found

[Yasbet_Alvarez]

We made a migration to the most current version of sap commerce 2211, the normal storefront works correctly but the jsstorefront application is not working correctly:

Access to XMLHttpRequest at 'https://api.{url}-{enviroment}-public.model-t.cc.commerce.ondemand.com/occ/v2/{site}/users/current' from origin 'https://jsapps.{url}-{enviroment}-public.model-t.cc.commerce.ondemand.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

An extension was created with the following webroot:

ext.newextensionwebservicesocc.extension.webmodule.webroot=/occ/v2

In addition, the properties were added to the manifest.json file:

...
{
  "name": "api",
  "properties": [
    {
        "key":"xss.filter.header.X-Frame-Options",
        "value":""
    }
  ],
  "webapps": [
      {
          "name": "newextensionwebservicesocc",
          "contextPath": "/occ"
      },
...

The following properties were also added:

## CORS configuration ##
########################
corsfilter.newextensionwebservicesocc.allowedOrigins=*
corsfilter.newextensionwebservicesocc.allowedHeaders=origin content-type accept authorization cache-control x-anonymous-consents x-profile-tag-debug x-consent-reference
corsfilter.newextensionwebservicesocc.exposedHeaders=x-anonymous-consents

 Do you know what configuration is needed for it to work correctly?
