Uncaught error in /rows on big datasets
For some datasets, for which the parquet files have been uploaded (or copied) with multiple commits (see https://github.com/huggingface/datasets-server/issues/1349) like `atom-in-the-universe/zlib-books-1k-50k`:

```
tiiuae/falcon-refinedweb
marianna13/zlib-books-1k-500k
atom-in-the-universe/zlib-books-1k-50k
atom-in-the-universe/zlib-books-1k-100k
atom-in-the-universe/zlib-books-1k-500k
atom-in-the-universe/zlib-books-1k-1000k
mlfoundations/datacomp_1b
```

the parquet files exist, all the steps are OK, but we get an uncaught error on /rows (in services/api):
