thread '<unnamed>' panicked at 'called `Option::unwrap()` on a `None` value'

[homehappily]

When I run

RAYON_NUM_THREADS=6 CUDA_VISIBLE_DEVICES=0 python3 rest_test.py I encounter the following error:

thread '' panicked at 'called Option::unwrap() on a None value', src/lib.rs:282:53

The first time, reinstalling the environment solved the problem.However, after I rebuilt a new large datastore, the same error appeared again.Meanwhile, running with the small datastore works fine. Could you help me understand what the issue might be?
