Parser breaks when there are Charts

[pxlmnstr]

I am unable to parse a Keynote file that contains a ChartDrawableArchive. As soon as I delete the used pie chart from the slides, parsing works. Here is the stack trace:

Traceback (most recent call last):

KeyError: 10000

During handling of the above exception, another exception occurred:

The above exception was the direct cause of the following exception:

Getting the same error here trying to parse a deck with charts. Were you able to figure out a workaround for this by any chance..?

Same issue here

My only Workaround was to remove the charts which was okay-ish for my use case.

I get similar problems when a Keynote file contains tables.
