# [Preview says agents get full HTML](https://rebilder.com/help/troubleshooting/preview-shows-html)

- **Summary:** The amber verdict means the gateway didn’t answer on that URL: not installed, not covering that route, or (on Shopify) you previewed the wrong path.

“Agents currently get your full HTML. Install the gateway to serve them clean markdown” means the agent-side request came back as ordinary HTML. The common causes, in order:



## Likely causes

- The gateway isn’t installed yet; see “Install the gateway on your store.”
- It’s installed, but not on that route. The integration declares which paths it fronts (typically products, policies, and collections), and a URL outside those paths passes through to HTML by design.
- Check the source mapped to the URL. Products, policies, catalogs, documents and collections each need the appropriate resolver; unmatched paths pass through to HTML.
- Shopify app-proxy installs serve agents on the proxy path: preview `https://yourstore.com/apps/rebilder/products/…`, not the canonical product URL. The canonical URL showing HTML on both sides is expected on Shopify.
- A data source failed for that URL. The gateway is deliberately fail-safe: if rendering markdown fails, the request falls through to your normal HTML rather than erroring, so a broken source looks like “agents get HTML,” never a broken store.
