Dataset viewer gives error "Bad split" if the name of the split is not "train" #3233
Description
Below is a screenshot of the Dataset viewer error I see after uploading this dataset: https://huggingface.co/datasets/roemmele/SceneIllustrations
I've only been able to resolve this error by renaming the test split to train (which is an inaccurate name for my dataset since it consists of a test set only).
Also, here's the discussion I previously opened regarding this, which includes some troubleshooting that ultimately didn't resolve the issue.
