NewtonSoft.Json Exception in Nuxt3 Application GitHib Actions Build

Question

We are currently experiencing a NewtonSoft.Json build issue in GitHub Actions for a new Nuxt3 static web app. The application builds and runs perfectly locally (npm run dev) but fails the build/deploy process when trying to deploy to Azure via GitHub actions. The exception being thrown during the build and the GitHub actions workflow yaml file are shown below:

`**`Build Operation ID: 75d5ecf1017c042b
OS Type           : bullseye
Image Type        : jamstack

As part of my troubleshooting I also scaffolded a barebones Nuxt3 Static Web App with nuxi and provisioned a new Azure Static Web App and the application deployed without issue. However, once I integrated the code from the problematic application, I once again started receiving the above exception. The problematic application was also deployed as-is to Vercel without issue so it appears that this is an Azure-specific deployment issue. At the end of the day I'm not quite sure why we are getting a Newtonsoft.Json.JsonReaderException on a Nuxt3/node app as this is something I would expect to see on a .net app at runtime.
