Errors when trying to deploy on Render

[DKBoston15]

I'm struggling to get AdonisJS v6 to build and run on Render.

Build Command in Render npm run build
Start Command in Render npm run start

Package.json Scripts

  "scripts": {
    "start": "node build/bin/server.js",
    "build": "node ace build --ignore-ts-errors",
    "dev": "node --import ./start/tracing.js ace serve --hmr",
    "test": "node ace test",
    "lint": "eslint .",
    "format": "prettier --write .",
    "typecheck": "tsc --noEmit"
  }

I've tried a dozen different things, but in all scenarios I end up with one error or the other. The most common error is

 node ace build --ignore-ts-errors
node:internal/modules/esm/resolve:857
  throw new ERR_MODULE_NOT_FOUND(packageName, fileURLToPath(base), null);
        ^

}
Node.js v22.12.0
==> Build failed 😞

I also run into scenarios where the server.js file is not in the build/bin folder.

I have a port env variable set to 0.0.0.0.
I also have NODE_ENV directly set to production, even though it should do it by default in Render.

I'm kind of lost at this point, and would appreciate any help that someone can offer. Has anyone else deployed to Render successfully?

Running pnpm build (node ace build), I get the following message in the terminal. I use pnpm, but same principle applies.

╭────────────────────────────────────────────────────────────────────────╮

Using this, the following settings work for me on Render:

• Render build command: pnpm install --frozen-lockfile && pnpm run build
• Render start command: cd build && pnpm i --prod && node bin/server.js (this is likely the key)
• Port is set to 0.0.0.0

But this installs the development dependencies, which is why it works — the package ts-node-maintained is listed as a development dependency, and when it's installed, the build runs without issues.
