A co-worker of mine create an article as a test, and subsequently deleted it. However, it didn't disappear from our live page.
I have tried creating another article, with the same UID and archiving it, as you can see below.
I apologize for the late response. I was out of the office last week.
I have checked your repository and found that you don't have any test UID documents, so API is returning 0 documents which is correct because you already have removed, & unlocked an old UID value from a document. The URL is still live with this UID means we save all the previous UID values of a given document so that your old links won’t be broken on your site when you change a UID value. Setup a rerouting system (recommended)
For this, you need to make a check in your routing system. If the UID used isn’t the current UID value, something like this:
if (uid !== document.uid)
Then redirect to the url that uses the current UID.
This will ensure that old links aren’t broken and that all old links will redirect to the current one.
