- Have an iFrames macro on a page with no 'src' parameter.
- This can be reproduced by modifying the storage format and removing the parameter manually
- Speculation is that some customers may have ended up with macros in this state due to coming from a much older version of Content Formatting, where the parameter was not required
- Run the iFrames auto-import tool
The tool completes as normal
Hangs at 0% and exceptions in logs:
In GetExistingUrlsAutoPopulateStage we're getting each iFrame's src parameter value in order to validate its length - this is throwing an exception when src is null, which evidently causes the import task to hang at 0%.
Manual testing should validate that the import tool runs and completes when the instance has one or more macros with no 'src' parameter.
