I just did a test on their validator: HTML5 Validator
And I got one warning:
The creative calls a file hosted by a third party, which could be an issue if the third party cannot handle the high server load that display campaigns typically generate. To learn more about the referenced file and to confirm that the third-party server will be able to handle the load, contact the creative developer.
More details:
Source: EXTERNAL_FILE_REFERENCED found in index.html: https://cdn.jsdelivr.net/gh/tumult/hype-runtime/HYPE-648.full.min.js
Since the runtime is hosted on a server that can handle high load, you should be good to go.
Here is the export script I used (which now includes the CDN URL)
DoubleClick DCM Hype CDN.hype-export.py.zip (4.3 KB)
Can you test this out and let me know if you hit any issues?
