Error when setting up the Dataset Viewer - StreamingRowsError

Hi! I have a problem with uploading MOCKS dataset to enable our prepared custom splits. I’ve followed guides and tutorials to do it in proper way but each time I got the same error. I want the viewer to show audio id, audio and transcription, and when I want to get the transcription from the tsv file (transcriptions are in second column) and use proper index (row[1]) - I got IndexError: list out of range. Could you please help me figure this out? I’ve tried to read the tsv files without download_and_extract function and the result is the same. Thanks in advance!
