Issue
- I have an issue with the RSS publisher widget. I add an RSS publisher widget to a page and configure it to render a URL.
After saving the configuration, an error in the UI appears and a log error is thrown.
Reproduction Steps:
1. Start QR 2024.q2.12 + liferay-dxp-2024.q2.12-hotfix-38.zip
2. Go to Site Builder --> Pages and add a page
3. Add to the page an RSS Publisher widget.
4. Configure the widget, at the Feeds tab enter the following URL in the URL field: https://www.augsburger-allgemeine.de/augsburg/rss and click o n save.
5. Close the configuration popup.
Expected Result: The Feed should be rendered with no issues.
Actual Result: A UI error appears in the RSS publish widget:
”RSS Publisher is temporarily unavailable” and an error in the log is thrown. See the below snippet:
