No possibility to update public code graph anymore?

I used to be able to see the code graph status of repositories like github.com/xwiki/xwiki-commons, github.com/xwiki/xwiki-rendering and github.com/xwiki/xwiki-platform on sourcegraph.com. As the automatic indexing was failing, on November 15, 2023, I generated index files using scip locally and uploaded them. These indexes also still exist on the platform, you can still select in the “code intelligence preview”.

However, since some time (I don’t know when), I’m no longer able to see the code graph status. I’ve also just tried generating and uploading a new index, and it says “unauthorized upload” even though I regenerated and updated the GitHub token. My status on these repositories is unchanged, I’m an owner of the xwiki GitHub organization.

Is this change intentional? Is there any other way to update the code graph, e.g., by fixing the automatic generation?
