GitHub Action Deployment Successful, but functions not deploying

Short Description: Azure/static-web-apps-deploy@v1 GitHub Action appears to deploy successfully, but functions are not deployed. No Visible errors in logs.

I've been struggling with this for a few days. I have a React SWA with TypeScript functions (currently 9 API functions), and Postgres DB. Everything is working fine locally. I've then check-in code, do a pull-request, and the GitHub Action runs and completes successfully. The React site loads fine, and authentication is working, but all of the functions return 404. It seems they aren't deployed. In the VS Code Azure extension, when I expand the Function node for the SWA, it says no functions found.

My first thoughts were something with Prisma was failing, but Prisma seems fine. The build commands are completing, and the migration and seed commands are finishing successfully.

I've trying different things in the yaml and build scripts but can't find the problem. I'm thinking I may just start over with clean new application, and work by way back to this point.

Here's some important areas of the deployment logs showing success.

Here's the VS Code extension show no functions have been uploaded (there should be 9 functions)
