Describe the bug
I have a workflow that draws from Youtube. For many months, I have used it and it worked perfectly but now it seems to fail.
When I enter the link https://www.youtube.com/feeds/videos.xml?channel_id=XXXX in my browser, I get all my data.

Expected behavior
I expect the workflow to get the required contents and updated my README.md accordingly.
