Failing to Build/Deploy portfolio website

Hello,
I am trying to deploy my personal portfolio website that I have linked to a github repository, but it fails to build. My Netlify site name is " fantastic-concha-21d80c".
Here is the build log. Thanks in advance for your help!

Hey @gmPuryear

Appears there is a slight issue with the submodules in the projects directory. I see there are three, however none of them link to anywhere when viewed on GitHub suggesting (as per the error message) there is no URL present, or the URL is invalid.
