Hint for HELP

I’ve been going in circles for a few hours now. Have made no progress. I’ve managed to find a mention to Shiv, but have failed to find any credentials. There was a header with some a request and response but I have not found anything useful. I have also been searching how to leverage n***.js but have had no luck. Just a bunch of failed attempts at getting a reverse shell by listening to port 80 while trying different q=require’… commands in the url, which is from googling abunch of stuff about it. The learning curve I am attempting to climb is a bit steep, can i get a push?
