The invalid Arrow data comes from pyarrow's JSON reader, not from `datasets`: when a list column's first non-empty value in a block starts with `null` (e.g. `{"a": [null, 1]}`), type inference can drop the leading null while the offsets still count it, so the table's list offsets span mor... | https://api.github.com/repos/huggingface/datasets/issues/8604/timeline | null |
