Hybris OOTB have a bug in getting PageModel for multicountry content catalog. Issue is located in DefaultCMSPageService.getPageForId(id) method, which executes flexible search query for all session catalogs and returns (AbstractPageModel) pages.iterator().next(). In most cases it will return root global catalog page instead of page from country specific content catalog.
In OOTB hybris smartedit throws FlexibleSearch errors on personalization view and most part of customization functionality doesn’t work. Exception will inform that there is an error in SQL syntax near UNION ALL.
Smartedit works perfectly on local environment, but after deploying on development environment (which is deployed with CI/CD pipeline) smartedit stops responding with endless loading.
