Thanks for taking the time to raise this issue. Would you be able to provide us with the PDF file you are using so we could try and re-create this issue?

Sure thing, the PDF is available here: julia-no-text-short.pdf

Able to reproduce when installing with npm install. Installing with yarn gave me a likely unrelated GRPC build error.

For what it's worth, I tried again using the fork from @ailintom, but still had the same issue.

Let me know if there's anything else I can do to help!

This is related to issue 2462 with the jsPDF dependency. You can fix this by editing package.json to use an older version of jsPDF before the error was introduced. Simply change line 14 from "jspdf": "^1.3.5", to "jspdf": "1.3.5", then re-run npm install.
