I noticed an issue with the “hs theme preview”, when I up and run the example page which contains the global module (with modified settings in the global editor) - the data is missing - it looks like HS doesn’t fetch the data but instead serves the ones defined from the fileds.json file ---

@Dawidk Thanks for confirming on that part, as a next step we must review environment variables, and local server configurations. **Regards** ---

So the issue is on the HS side? And I should wait for the fix? ---

Hi @Dawidk, you’re guessing right. The “hs theme preview” command creates only a local preview of the locally available theme elements like CSS, JS, JSON, modules and templates. **It is not connected to HS in any way.** Therefore - changes you apply to global modules inside your portal won’t be displayed in the theme preview. Kinda odd, but the theme preview command was implemented to let a developer check for major issues before uploading it to a portal. Since even the default placeholding menu we all know (the one that gets displayed in a menu module until you select a real menu) is rendered by HubSpot - not a template or JSON file anyone outside of HubSpot can access. And this leads to the case that a menu is not being rendered in the hs theme preview. If you like to test the menu - I’d recommend to upload the theme to a test portal and test the “real case scenario” in this test portal. Once testing is done, move the files to the live portal. best, Anton ---

Hi Anton! Let’s say I have classic modules (local and native - like RichText) that are on template X and based on it I have page Y. When I modify content on the page (page Y) the changes are visible when I preview the page in local mode. ![Dawidk_0-1723391195588.png](https://d2qpr2jzcazej7.cloudfront.net/original/3X/1/5/151728d290e2257dacaa55ffe6522f7797ad27a4.png) So **since the data are not connected** **with HS (as you wrote)**, the data should not be visible as well but I can see the changes, that’s why I assumed that the lack of data on the global module is a bug ---

The most interesting thing is that when I use a global partial containing non-global modules (but HS treats them as global), everything works fine and I can see the updated data.
