[BUG] Open Deep Research use citations in final report but cannot access manually via web browser

[Rhett-Ying]

Describe the bug
I am using claude 3.7 as the backend model with Open DR. In the references section of final report, I find some of the URLs cannot be found via manually access on web browser. It prompts file not found or error 404, page not found. For example,

https://github.com/huggingface/smolagents/blob/main/examples/open_deep_research/app.py
https://salt.security/resources/state-of-api-security-report
https://www.actian.com/resources/whitepapers/data-engineering-guide

So I am wondering how does the Open DR access such URLs when generating report. Or are these URLs really used?

Code to reproduce the error
https://github.com/huggingface/smolagents/blob/main/examples/open_deep_research/app.py

Error logs (if any)

Expected behavior

Packages version:

That text is generated by the model you are using. I guess those URLs were operational when your model was trained.
