Error "A notebook already exists at that URL" while not existing.

When I tried to set a custom URL, say “xyz”, for my notebook, I got an error “A notebook already exists at that URL.” even though I am not using that URL actually. In fact, I accessed the URL and see the error “You either don’t have permission to view this notebook, or it doesn’t exist.” So, yes, it does not exist indeed. It would be nice to know is there anyone else who experienced the same phenomenon or how I can solve this problem.

Are you making the notebook inside a team? If so, someone else could’ve made a notebook with that URL that you’re not able to access, and you’d see that error page at the URL.

Is it possible that you previously trashed a notebook with that URL? When you delete a notebook, it doesn’t release its URL back into the pool of available URLs, and if it’s been more than 30 days since you deleted it, you’d see that error page at the URL.

Otherwise it sounds like it could be a bug! Feel free to DM me details of your specific situation and I can look into it.

Thank you so much, @tophtucker, for your quick and kind comment.
My notebook is private; I believe the URL is only available for me.

As for the deletion of the notebook with a custom URL, your comment is very informative to me.
But honestly speaking, I’m not perfectly sure whether I deleted the notebook with that URL more than 30 days ago.
I, however, believe I did not do it because I recently recognized this custom URL function.

I apologize if it is true that I DID; I’ll send you DM about my specific situation. Thanks!!

To me, that’s a bug. Once the notebook is permanently gone, what’s the purpose of withholding the URL from the available pool?

According to Mike, “the intent of this design is prevent links and imports from unexpectedly changing from one notebook to another”.

@mcmcclur Thanks. Though, to me it appears to increase the potential for that outcome instead of preventing it.

Then, rather than @mcmcclur , I guess you mean @mbostock. :slight_smile:

Implicitly we are saying that it’s better for the link to be broken because that notebook no longer exists (because it was trashed), rather than to point to a new notebook which may or may not be related.

I understand and support that philosophy, @mbostock, as well as @kentr’s feelings.
However, my situation seems a bit irregular; I thoughtlessly deleted my named (published) notebook before the custom-URL feature was implemented and ended up losing its URL permanently. I hadn’t realized the necessity to unpublish it before the deletion then.
