Describe the bug

When deploying a trigger.dev project with Prisma schema using the typedSql preview feature, the build fails during the Prisma generate step with an "Unknown type" error. The error does not occur in local development.

To reproduce

trigger.config.ts

export default defineConfig({
  project: 'my_project_id',
  machine: 'micro',
  build: {
    extensions: [
      prismaExtension({
        typedSql: true,
        schema: 'prisma/schema.prisma',
        directUrlEnvVarName: 'DIRECT_DATABASE_URL',
      }),

      // ... other extensions
    ],
  }
})

package.json (relevant sections)

{
  "prisma": {
    "schema": "prisma",
    "seed": "bun prisma/seed.ts"
  },
}

prisma/schema.prisma

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["typedSql"]
}

datasource db {
  provider  = "postgresql"
  url       = env("DATABASE_URL")
  directUrl = env("DIRECT_DATABASE_URL")
}

Prisma folder structure

prisma/
├── schema.prisma
├── seed.ts
├── migrations/
├── sql/
├── model.prisma
...other prisma model files

Steps to Reproduce

1. Create a trigger.dev project with Prisma extension using typedSql: true
2. Use a multi-file Prisma schema structure (schema split across multiple files)
3. Include SQL files in prisma/sql/ directory
4. Run bunx trigger.dev@3.3.17 deploy
5. Build fails during Prisma generate step

Additional information

The project uses a multi-file Prisma schema structure where models are split across separate .prisma files
