Error: Loading Thumbnails

[ch-sander]

I fail uploading thumbnails als ZIP, named as ID.jpg (no subfolder):

main-5BZK4IIQ.js:4216 [PyodideWorker] Thumbnail error: undefined
(anonym) @ main-5BZK4IIQ.js:4216

Loading the CSV (separate upload) works fine!

[ch-sander]

magnetism.zip

[ch-sander]

glyphboard.csv

Dataset must be named magnetism.csv, thumbnail file magnetism.zip for me this works after renaming the CSV file and ZIP you provided. Note that more help and guidance is due to be implemented.
