Hi @dlu, this is an issue that others have run into before, too. A while back, I pushed a fix to the proximal issue of the script trying to remove items that don’t exist in the list, but this doesn’t necessarily fix the ultimate issue with the input data that causes that script to fail.
@corneliusroemer, is there anything you’d suggest here? My first thought is that @dlu could try running the mpox workflow from the fix-fix-tree branch in the PR linked above…
