I have been using path aliasing in my NextJS project for months now, but I recently changed to a custom server where I am using ts-node to run my code, and my path aliasing just doesn’t work anymore.

I run ts-node server.ts with this tsconfig:

{
  "compilerOptions": {
    "lib": [
      "dom",
      "dom.iterable",
      "esnext"
    ],
    "typeRoots": [
      "./types"
    ],
    "allowJs": true,
    "skipLibCheck": true,
    "strict": true,
    "noEmit": true,
    "esModuleInterop": true,
    "module": "CommonJS",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "jsx": "preserve",
    "incremental": true,
    "plugins": [
      {
        "name": "next"
      }
    ],
    "baseUrl": "./",
    "paths": {
      "@/*": [
        "./*"
      ]
    },
  },
  "include": [
    "next-env.d.ts",
    "**/*.ts",
    "**/*.tsx",
    ".next/types/**/*.ts"
  ],
  "exclude": [
    "node_modules"
  ]
}

and get this error: Error: Cannot find module '@/lib/mock-db'. Note, when I change the import to a relative path like ../../lib/mock-db, it works fine.
