Open unlisted jobs not accessible via the API

[njt1982]

Hi,

We have several jobs listed in Lever as Open but Unlisted.

We can access them by direct URL in HTML fine, but they are not accessible via the API.

It's fine that they're not listed but I think they should be accessible (and POST'able to) via specific jobs URLs.

When I try to GET the job directly I get this response:
{"ok":false,"error":"Document not found"}

So, to be clear:
https://jobs.lever.co/[SITE]/[UUID] < This works fine (shows the job and I can get to the apply form too).
https://api.lever.co/v0/postings/[SITE]/[UUID]?mode=json < This does not work, shows the above error.
