### Description

The dataset viewer is not working for dataset birgermoell/synthetic_compassion.

Error details:

```
Error code:   ClientConnectionError

```
I'm getting this error when creating my new dataset. I have a metadata.csv file in the following format and a data folder with mp3 files named 1.mp3 2.mp3 and so on.
The only thing I can think of is that the order of the files aren't 1.2.3 in the metadata.csv file but I can't see why that should matter.
