KeyError: 'frames' when trying to download some presentations

[gonzalognzl]

While trying to download some presentations, I get this error message:

  File "prezi2pdf.py", line 67, in <module>
    download_presentation(id)
  File "prezi2pdf.py", line 46, in download_presentation
    total = len(data['frames'])
KeyError: 'frames'

For instance:
https://prezi.com/p/i4dvbt-cfhdt/introduccion-a-la-archivologia-gestion-documental-2023/

I've seen something similar reported at #2 , but this is prezi.com/p actually.
Thanks for any support!

I've just realized it was the "-" char in the id.
