Script Engine Initialization Issues -- Debian

[SUD0-404]

Hello!

I'm looking to use this tool for some testing. However, when I went to update the database, and to run it for confirmation afterward, it had an error. It was as follows:

Starting Nmap 7.70 ( https://nmap.org ) at 2021-11-14 21:28 EST
NSE: failed to initialize the script engine:
/usr/bin/../share/nmap/nse_main.lua:259: /usr/bin/../share/nmap/scripts/vulners.nse:7: une

QUITTING!

This was the same error as when trying to update the nmap script DB. I'm not sure if it's a mistake on my part or an error with your code, but based on the error, it looks like a code syntax error.

Thanks so much for your help!
