Hi at ALL,
I got this error while running the script.

How to fix this ?

Here the nse_main script:

nse_main.zip

Thanks

I had the same problem. My error was: I copied the file from this side - therefore it was in html-format (First lines empty). You have to save it as plain test (First line: local nmap = require "nmap")

Hi,
Can anyone help me with this?

I have a similar problem, I'm new to VAPT and I'm using GUI for windows, this is what I got when I used this script from nmap online guide [nmap -p 80 --script http-default-accounts.routers xx.xx.xx.xx]. I borrowed the script from here : https://nmap.org/nsedoc/scripts/http-default-accounts.html

Nmap output begins below this line:

NSE: failed to initialize the script engine:

C:\Program Files (x86)\Nmap/nse_main.lua:823: 'http-default-accounts.category' did not match a category, filename, or directory

stack traceback:

[C]: in function 'error'
