HTML5 Debug Mode
From version 220.127.116.11.0, debug mode is available in the HTML5 Pulse SDK and all its derivatives (HTML5 Ad Player and all the HTML5 plugins). Debug mode enables the SDK to send log messages about what is happening in the integration to a console, and helps you to manually debug issues. The log messages relate to:
API calls received by the SDK
Events sent by the SDK
Errors reported by the integration
Internal logic of the SDK
When errors are logged, the message may contain a VAST error code. The VAST Error Codes Table in IAB's VAST 4.0 document contains the descriptions for these error codes.
When to Use HTML5 Debug Mode
There are two main use cases for the HTML5 debug mode:
- Developers can use it during the development phase, to see if their integration with Pulse works as it should and all information is sent in the correct order to Pulse. More information about the expected exchange of information between Pulse and the integration can be found on the Pulse SDK Event Sequence Scenarios page.
- Ad operators can use it to investigate why a campaign with third party ads is not delivering. Some of the third party ad issues that operators may encounter are explained here.
How to Enable Debug Mode
- Add ?pulse_debug at the end of the URL where your integration is located. For example, mysite.com/player?pulse_debug.
In the debug console of your browser, enter OO.Pulse.debug = true while your browser is on the page where your integration is located. For example, in the Console of the Developer Tools of Chrome:
Add OO.Pulse.debug = true in your code, after loading the SDK. For example, in the body of the HTML page of your player, you could add:
Using Preview Mode to Debug a Specific Ad
Another part of HTML5 debugging is the preview mode, where you select to preview and possibly debug a specific ad. To use the preview mode:
- Add ?pulse_debug&pulse_preview=<UUID of the ad> at the end of the URL where your integration is located. For example, mysite.com/player?pulse_debug&pulse_preview=58f1a009-0bd1-47f9-ad3c-8946b1cf8863.
Third Party Ad Debugging
Media File Timeout
The third party provides a valid VAST ticket, but loading the suitable media file takes too much time:
Media File Not Found
The third party provides a valid VAST ticket, but the URL for the suitable media file is not valid:
No Media Files Present
The third party provides an invalid VAST ticket, because there are no media files present:
The log also contains the VAST error code telling you that the ticket's format is not according to the VAST standard.
Unsupported Media File Type
The third party provides a valid VAST ticket, but none of the media files have a compatible MIME type:
This error also occurs when a VPAID is passed that is not compatible with your integration.
Cross-origin Resource Sharing Issues
A third party VAST ticket or a media file is available, but it cannot be accessed due to a CORS issue:
The provider of the VAST ticket or asset should enable your domain to have access. Alert the advertiser of this issue.
