'PDFObjRef' object does not support indexing

Hi! I can't really debug this without the PDF that's causing a problem for you -- can you share it?

[travis-st]

I would love to, but it's proprietary and confidential. Sorry :(

FYI, experienced a different problem this time:

>>> pdf = pdfquery.PDFQuery("input/2015/12-Dec/17-Dec/17-12.pdf")
>>> pdf.load()

Any update on the "'PDFObjRef' object does not support indexing" issue?

I experienced this same issue, and also cannot share the PDF being used unfortunately.

I have a similar problem.

Here too. Same problem:
