Hello, New member here! Since I using this app is about a mouth ago, everything is fine at that time, recently I updated it and want to check out my data(500MB) can still working or not, but only thing I got is: ValueError: not enough values to unpack (expected 2, got 1) I thought maybe is my code…

Maybe interesting: [image] Show and Tell - dash-uploader (Upload large files) Dash Python Hi all, I had some problems with uploading large data files using Dash, and I bumped to the awesome package dash-resumable-upload (0.0.3) and the improved version (0.0.4) by github …
