I'm not sure if it matters or not but we are using yarn for this project.

I'll have time to check this out over the weekend and I'll let you know what's going on. To me, it looks like the node lock file hasn't been updated and you're missing some modules. I'd start by:

1. Delete the npm lock file
2. Run npm install

If that doesn't work, maybe try installing yarn and running with that.
