Hello @oren_clearya,

Thank you for bringing this issue to our attention, and I apologize for the delayed response. I attempted to replicate this using a similar setup, and scraping the XML document worked as expected on my end. Unfortunately, the linked run has expired, so I cannot investigate further or reproduce the issue.

It’s possible that the error was caused by a temporary issue or specific conditions during the run. If you encounter this problem again, please provide a fresh run link and any additional context, and we’ll be happy to assist further.

I’ll close this issue for now, but don’t hesitate to create a new one if needed. Thank you for your understanding!
