Tunnel-SSH doesn't connect to server successful in node application - node.js

Question

I'm trying to connect to a cloud server that runs my MongoDB from my local machine. I'm using tunnel-ssh within the Node.js application I'm creating, however, I seem to have multiple problems and I don't fully understand what's going on.
Problems
I'm not 100% sure I'm successfully connecting to the server. There's no error, however, when I console.log(server) it says _connections: 0,. see full log below.
If I am connecting and then I try to run the getDataFromMongoDB function it returns the error, EADDRINUSE: address already in use 127.0.0.1:27000.
I've been trying to wrap my head around this all day and I'm not getting anywhere. Please help.
Error 1 - Is server connecting
