See https://github.com/huggingface/dataset-viewer/issues/2766#issuecomment-2090443731

> For https://huggingface.co/datasets/re-align/UnifiedChat, for example, we have entries, including an error with LockedDatasetTimeoutError, for config `default`. But this config does not exist anymore.

In this case, the backfill process should have deleted all the cache entries for config `default`.
