ike-version error (table expected, got nil)

[xpelican]

First of all, thank you so much to everyone out there developing for nmap, your work is highly appreciated.

I had an error output from ike-version.nse. Looking up the error, I saw one thread listed on the nmap site that had similar (though not same) error output as the one I was getting. I tried applying the solutions presented in that thread and they did not work for me, lengthening the error output instead. (Seeing the thread is from 2013, I assume the fixes in that thread are probably already part of nmap's default installation at this point, hence how they broke my version of the script.) I've since reinstalled nmap to have its default files.

Here's the error I'm getting:

The destination machine is working as intended.

Thank you in advance for your help.

Did you find the solution? I have the same issue.
Thanks!

Nope, sadly I never figured it out!
