The dataset viewer is not working. I checked the JSON file has the correct structure.
Error details:
Error code: FeaturesError
Exception: ArrowInvalid
Message: JSON parse error: Column(/translation/zh) changed from string to number in row 2404

As you can see, the viewer is working now after having fixed the malformed JSON-Lines files.
Thanks, Albert, however the offending line is actually at line 7446 but not 2404. This could be a potential bug of the dataset loader.
