"Most middleware" issue with running node app.js from terminal

I'm new to node.js, and I can't seem to run my node app.js file after adding in a new file called projects.js with only this JS code:

exports.viewProject = function(req, res){    res.render("project");  };

This is a pre-coded project from my (useless) professor, and I'm getting this error:

I have Big Sur, uninstalled and reinstalled node, tried sudo, and it still doesn't work. Here is my app.js code as well, and I only added var project and app.get('/project'... etc).

Sorry if this is lengthy, I'm just trying to make it through online classes during a pandemic. Thanks!
