Trying to connect to MongoDB from a web server using Expressjs – CPanel

I’m trying to set up my website it’s already complete and it works locally on my computer but when I transferred it to a hosting site that uses cpanel. The contact page that uses Express as it’s backend wasn’t working. So I got access to the terminal and set up node js and all of the dependencies I am using through npm but I’ve run into this error concerning the connection to MongoDB I can’t figure out what to do.

I’ve tried various ways to remedy this but to no prevail. I figure it could be I don’t have mongodb in my path for the server but I wasn’t able to get access to add it so I didn’t try could that be it. If anyone has experience with mongodb and hosting websites your help would be greatly appreciated. Also I’m open to using a different database I just opted to use mongo for it’s simplicity.

So far i’ve been studying about how to make websites and webpages but I’ve never really encountered how to host these sites so when I made my website I wasn’t thinking how I could host it with it using nodejs/expressjs, mongodb, and even other modules such as handlebars and lightbox (which seem to be working).
