Exception: Missing /Root element

[shwetankarora]

I have run peepdf on a file using the following command on mac:

peepdf <filepath>

and got the following error in file .peepdf-error.txt:

Traceback (most recent call last):
  File "/usr/local/lib/python3.8/site-packages/peepdf/PDFCore.py", line 7705, in createPDFTrailer
    trailer = PDFTrailer(dict, lastXrefSection, streamPresent=streamPresent)
  File "/usr/local/lib/python3.8/site-packages/peepdf/PDFCore.py", line 4474, in __init__
    raise Exception(ret[1])
Exception: Missing /Root element

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/lib/python3.8/site-packages/peepdf/main.py", line 409, in main
    ret, pdf = pdfParser.parse(fileName, options.isForceMode, options.isLooseMode, options.isManualAnalysis)
  File "/usr/local/lib/python3.8/site-packages/peepdf/PDFCore.py", line 7153, in parse
    ret = self.createPDFTrailer(trailerContent, trailerOffset)
  File "/usr/local/lib/python3.8/site-packages/peepdf/PDFCore.py", line 7708, in createPDFTrailer
    if e.message != '':
AttributeError: 'Exception' object has no attribute 'message'

On the command line, I get the following error:

*** Error: Exception not handled!!


Please, don't forget to report errors if found:

	- Sending the file "/Users/shwetankarora/.peepdf-error.txt" to the author (mailto:peepdfREMOVETHIS@eternal-todo.com)
	- And/Or creating an issue on the project webpage (https://github.com/jesparza/peepdf/issues)

What could be the cause of this issue?
