Yash1709,
You have two options on how to fix this. You will have to navigate to the following location: Target > Setup > Properties
Option1: Delete the URL from the properties list.
Option2: Edit the property get the special property code and add it to the page code on that URL.
Both of these will make the error go away. If you can't figure out how to do it and are a supported user reach out to client care at: ttclientcare@adobe.com or 1 (800) 497-0335 x3
If this helps you don't forget to like and mark as helpful as that helps me
Hope you have a wonderful day.
