I found a similar discussion regarding file support issues: Not support for mp4?, which is currently unsolved [1].

Regarding your issue, MP3 files should be supported for audio uploads in Dify, as the platform supports file extensions like FLAC, MP3, MP4, MPEG, MPGA, M4A, OGG, WAV, and WEBM [2].

The error you're encountering might be due to a configuration issue or a bug in the version you are using. You might want to check the file type validation settings in your configuration to ensure MP3 is included in the allowed file types. The validation is handled in the FileUploader component and the backend FileService class, which checks against predefined lists of supported file extensions [3][4].

If the configuration seems correct, consider checking for any updates or patches that might address this issue in your current version.
