Hi!

for one of my slide decks I am getting the following error from decktape

Printing slide #4       ( 4/23) ...TypeError: Cannot read property 'dict' of undefined
    at parseXObject (/decktape/decktape.js:393:28)
    at /decktape/decktape.js:384:42
    at Array.forEach (<anonymous>)
    at parseResources (/decktape/decktape.js:384:25)
    at parseXObject (/decktape/decktape.js:403:7)

If it helps, the slide at question is available here: https://gitlab-nrw-workshop-2021-04.gitlab.io/workshop/slides.html#4

I am a bit lost, it would be nice to have a hint why it fails.

For some reasons, the PDF generated out of slide #4 contains a reference that cannot be resolved. so the following call returns an undefined result:

decktape/decktape.js

Line 392 in bb3c3a2

const object = page.node.context.lookup(entry);

Interestingly, I've been able to produce a correct PDF by returning early and skipping the unresolved reference:

test.pdf

It would be interesting to understand what is special in slide #4 that leads to that undefined result.

It should be fixed in version 3.4.1. Feel free to re-open if needed.
