I am following this tutorial: Creating a Simple RESTful Web App with Node.js, Express, and MongoDB | Christopher Buecheler - Web, Writing, Cocktails and More.

I get about half-way into it, and notice that my page is not reflecting the changes that I am making to my code. For example, I just added the input text fields, and all I see is an empty table with the headings. I do not see the text fields.
When I run "npm start", I get this error:
{ [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' }
js-bson: Failed to load c++ bson extension, using pure JS version
Could this be causing the issue? I am still able to load the page.

As I am new to this, I am not sure where to begin looking to fix this. Any help is much appreciated.
