Headers and Helix Configs in EDS Site created with Edge Delivery Services Template (universal editor , xwalk project)

I have created an EDS site using the "AEM Site with Edge Delivery Services Template 0.0.16" and set up configurations and headers within it. The paths JSON file in the repository has the necessary mappings. I can access the Helix config via https://main--***.aem.page/config.json, but any updates made and republished do not show up in the config JSON. Additionally, when attempting to load headers JSON via https://main--**.aem.page/headers.json, I receive a 404 error.

Please let me know why the headers json I am not able to view.
