Solutions

1. Ensure the presentation has at least one slide with content
2. Re-save from PowerPoint/Keynote as standard .pptx
3. Verify structure: unzip -l file.pptx | grep 'ppt/slides/'

import zipfile, re
with zipfile.ZipFile(path) as z:
    slides = [n for n in z.namelist() if re.fullmatch(r'ppt/slides/slide\d+\.xml', n)]
    if not slides:
        reject_upload('Not a valid PPTX (no slides)')

When it happens

Trigger: An empty presentation with zero slides, or a renamed zip that lacks the ppt/slides/ structure.

Common situations: Users uploading template files, empty decks, or renamed archives; also PPTX saved in unusual formats lacking standard slide parts.
