Hi @_anon_ymous_ ,
Root Cause Possibilities:
1. Missing clientId for Adobe PDF Embed API
2. Incorrect Context-Aware Config (CAConfig) path
3. Core Components version incompatible
4. PDF URL not set or invalid
5. Browser blocking insecure content (HTTP PDFs on HTTPS site)
6. Missing Dispatcher Rewrite Rules (if applicable)
1. Check Client ID Configuration
Based on your screenshot, clientId is present: 28b07c6be4d544f...
Ensure this is from Adobe’s PDF Embed API registration: Get clientId
2. Correct Context-Aware Configuration (CAConfig)
Make sure the PDF Viewer component is inheriting the config.
Your configuration should be under:
/conf/<your-site>/settings/wcm/core/components/pdfviewer/v1/pdfviewer
Ensure the page where you’re placing the PDF viewer has CAConfig properly set in Page Properties > Advanced > Context-aware Configuration Path pointing to /conf/<your-site>.
3. Core Components Compatibility
Your AEM 6.5 must have Core Components 2.12.0+.
Verify installed version:
http://localhost:4502/system/console/bundles/com.adobe.cq.core.wcm.components.core
Upgrade if needed: Download Core Components
4. Check Component AuthoringDid you provide a valid PDF URL in the component dialog?
It must be a publicly accessible PDF (or within AEM DAM).
If PDF path is relative or missing, the component won’t render.
5. Check Browser Console
Inspect browser Console (F12) for errors like:
Invalid Client ID
PDF URL not found
Mixed content error (HTTP PDF on HTTPS site)
6. Dispatcher Configuration (If Used)
Ensure that PDF MIME types are allowed in Dispatcher.
Add in dispatcher.any:
/0040 {
/type "allow"
/extension "(pdf)"
}
Flush Dispatcher Cache if needed.
Quick Test (Bypass All Issues)
Place PDF URL from AEM DAM:
/content/dam/your-site/sample.pdf
Open page in Preview mode.
If still blank → It’s likely CAConfig or Client ID not linked properly.
Use Embed Mode (Debug)
In the component dialog, enable Embed Mode and inspect the iframe being rendered. If the iframe is not rendered, it’s definitely clientId or PDF path issue.
