It seems like you're encountering an issue with the X-Ray panel, but please note that my last knowledge update was in September 2021, and I don't have real-time information on specific software updates or changes beyond that date.

If you're experiencing a problem where you're getting a duplicate URL error while adding a new task in the X-Ray panel, here are a few steps you can take to troubleshoot the issue:

1. Check for Typos: Double-check that you're entering the correct URL. Sometimes, a small typo can lead to this error.

2. Clear Browser Cache: If you're using a web-based application, try clearing your browser's cache and cookies. Sometimes, stored data can cause unexpected behavior.

3. Verify the URL Format: Ensure that the URL you're entering is in the correct format (e.g., "https://www.example.com"). Incorrectly formatted URLs can lead to errors.

4. Check for Special Characters: Make sure there are no special characters or spaces in the URL. Some systems might not handle them well.

5. Update the Software: If this is a known issue, the software developers may have released an update to fix it. Ensure you're using the latest version.

6. Contact Support: If the issue persists, reach out to the support team for the software or service you're using. They may have specific troubleshooting steps or be able to provide a solution.

7. Community Forums and Documentation: Check community forums or the official documentation for the software. Other users may have experienced a similar issue and there might be a known workaround or solution.

8. Report a Bug: If you've tried the above steps and still encounter the problem, consider reporting it as a bug to the developers. They can investigate further and work on a fix.

Remember, since my information is current as of September 2021, there may have been updates or changes to the software after that date. If the problem persists, I recommend checking the latest resources or contacting the support team for the most up-to-date information.
