Uncaught TypeError: Error resolving module specifier “@polymer/polymer/lib/legacy/polymer-fn.js”. Relative module specifiers must start with “./”, “../” or “/”.

I have been going through the process of upgrading my project from Polymer 2 to 3.0. Currently I am able to get my components to load if I run polymer serve. However, I am needing to actually build the project using IIS Express. Whenever I run the project it gives me the error: Uncaught TypeError: Error resolving module specifier “@polymer/polymer/lib/legacy/polymer-fn.js”. Relative module specifiers must start with “./”, “../” or “/”. The file that it is pointing to is iron-selector.js. I'm not too sure what that file does with my current project
