Hi

I'm attempting to insert JS that opens the URL whenever the user opens the PDF. Whatever JS I add, it executes it twice. In my scenario, Adobe Acrobat is alerting me about security twice because the same JS was executed twice.

Environment

Plaform: Linux-4.15.0-108-generic-x86_64-with-Ubuntu-18.04-bionic
PyPDF2 Version: 1.26.0
Python : 3.6.9

Code + PDF

from PyPDF2 import PdfFileWriter, PdfFileReader

output = PdfFileWriter()
ipdf = PdfFileReader(open('test.pdf', 'rb'))

for i in range(ipdf.getNumPages()):
	page = ipdf.getPage(i)
	output.addPage(page)

with open('updated_pdf.pdf', 'wb') as f:
	output.addJS('app.launchURL("https://google.com/", true);')
	output.write(f)

test.pdf
updated_pdf.pdf

Todo:

JS should be executed only once
