Is it possible to make Next.js keep the contents of that folder?

I'm working on implementing a Sanity's new Create feature. It requires couple of files to be in a specific location. I'm using version 14.3.2 of Next.js and the app router. My app folder structure looks like this:

1
├── app
2
│   ├── (studio)
3
│   │   ├── admin
4
│   │   │   ├── [[...index]]
5
│   │   │   │   └── page.tsx
6
│   │   │   └── static
7
│   │   │       └── .gitkeep
8
│   │   │     
9
...

On build, a script runs and generates two JSON files in the /app/(studio)/admin/static directory, and I've confirmed the files are generated during the build by listing the directory contents in the build script. The build logs show the files were created:

When checking the build's files, though, the json files in the screenshot above don't exist. This is what shows up in the deployment's source/output files:

Here's an excerpt of my run script that generates those files:

1
"scripts": {
2
    "prebuild": "npm run typegen && npm run extract-manifest",
3
    "build": "next build",
4
    "start": "next start",
5
    "extract-manifest": "cd src/sanity && sanity manifest extract --path '../app/(studio)/admin/static' && ls -all '../app/(studio)/admin/static'",
6
    "typegen": "cd src/sanity && sanity schema extract --path ../../sanity-schemas.json && sanity typegen generate"
7
  },

I'm not sure if this is related to the route group, opitonal catch-all, or something else entirely. Ultimately I need to be able to populate the admin/static folder with the Create json files created during build. Any tips on how to achieve this?

Thanks!

Edit: I've added the following to my next config and am testing things now.

1
  experimental: {
2
    outputFileTracingIncludes: {
3
      '/admin/static': ['./src/app/(studio)/admin/static/**/*'],
4
    },
5
  },
