I am having an odd error while essentially following the library

Hi! I'm sorry about your trouble, but it seems as if one of your .pptx files can't be decompressed by jszip. You could e.g. try to manually extract the contents of base.pptx, templateRef.pptx and generated.pptx and see which one is affected. (try to rename them to .zip and use e.g. 7zip to inflate and see what happens)

Did you create all of your template files with PowerPoint? If not, try to open and save the files in PowerPoint.

Please let me know if I could help.

I'm also seeing this: https://github.com/Stuk/jszip/issues/543. It could be a problem with larger files.
