I think I’ve figured out the cause. (Even though it didn’t exist when the space was created, it still worked.) There was a change that made it so that it would no longer work unless the **HF\_TOKEN** secret was set, but the template didn’t support it.

If you set your valid READ token to the **HF\_TOKEN** secret, it should probably work.
