TypeError: 'NoneType' object is not subscriptable

[Gengmaosi]

Excuse me, when we try the TabPFN today, the InternalServerError occurs, and the detailed information is 'TypeError: 'NoneType' object is not subscriptable.' Could you please check the problem for the InternalServerError?

Hello, I am also getting the same error, did you get any solution for this?

Hi both, thank you for the report!
@brendan-priorlabs, is this one of the issues we have fixed recently?

@Gengmaosi, @deluznalwings, sorry for the trouble here! This issue is somewhat misleading because we're currently not cleanly propagating errors from our inference backend up the stack. This turns a larger class of errors into 'TypeError: 'NoneType' object is not subscriptable.' We have addressed some of the underlying errors in recent weeks which should help. There's also an open high priority issue in our internal tracker for improving these error messages.

If you're still able to produce this exception, could you send me the precise timestamp (with timezone) of when it occurs? I would be very interested in digging into the backend logs for the root cause. Thank you!
