Hi, recently I am having a problem with dataset viewer. I cannot get the preview of audio files in my dataset. I am getting this error :
`ERROR: type should be audio, got [{ "src": "/static-proxy?url=https%3A%2F%2Fdatasets-server.huggingface.co%2Fassets%2Fj-krzywdziak%2Ftest%2F--%2FTest Dataset/test/2/audio/audio.mp3", "type": "audio/mpeg" }, { "src": "/static-proxy?url=https%3A%2F%2Fdatasets-server.huggingface.co%2Fassets%2Fj-krzywdziak%2Ftest%2F--%2FTest Dataset/test/2/audio/audio.wav", "type": "audio/wav" }]`
Audio files are zipped and are in wav format. Anyone have any idea?

Hi ! Which dataset is it ? The audio type must contain either
- a list of strings pointing to the WAV files
- a list of dictionaries with “bytes” and “path” field - containing the file bytes and the file name or path

Your code looks all good to me, this sounds like a bug on our side. I’m forcing a refresh of your dataset preview. If it persists, please open an issue at [GitHub - huggingface/datasets-server: Lightweight web API for visualizing and exploring all types of datasets - computer vision, speech, text, and tabular - stored on the Hugging Face Hub](https://github.com/huggingface/datasets-server)

@severo fyi - it’s a duplicate of [Problem with Dataset Preview with audio files](/static-proxy?url=https%3A%2F%2Fdiscuss.huggingface.co%2Ft%2Fproblem-with-dataset-preview-with-audio-files%2F31475) and the error is caused by a space symbol in the config name, you already opened an [issue for that](https://github.com/huggingface/datasets-server/issues/853) 🙂
