Recent Error parsing Cloudflare IUAM Javascript challenge
See original GitHub issueHello, I’m getting the IUAM parsing error since a day. This might be the same as #192. I cannot verify if the remote has changed its CF settings. Using cfscrape 1.9.5 in a python3 virtualenv.
I’ve added 3 debug lines to cfscrape code: dumping UA before/after randomization and dumping body in solve_challenge() exception message.

You can fix it by changing Line 122 in
__init__.py
to this regular expression:js = re.sub(r"a\.value = (.+ \+ t\.length(\).toFixed\(10\))?).+", r"\1", js)
This should now be fixed. Please see if
pip install -U cfscrape
resolves the issue.
