Trying to use Arktype with nestjs module problems

I don't undestand why i'm getting problems with 
Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/kordian/Projects/kindora-backend/node_modules/.pnpm/arktype@2.1.20/node_modules/arktype/out/index.js from /Users/kordian/Projects/kindora-backend/dist/src/database/pagination.types.js not supported.
Instead change the require of index.js in /Users/kordian/Projects/kindora-backend/dist/src/database/pagination.types.js to a dynamic import() which is available in all CommonJS modules.
    at Object.<anonymous> (/Users/kordian/Projects/kindora-backend/dist/src/database/pagination.types.js:4:19) {
  code: 'ERR_REQUIRE_ESM'
}

I'm using this tsconfig 
{
  "compilerOptions": {
    "module": "nodenext",
    "moduleResolution": "nodenext",
    "esModuleInterop": true,
    "isolatedModules": true,
    "declaration": true,
    "removeComments": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "allowSyntheticDefaultImports": true,
    "target": "ES2023",
    "sourceMap": true,
    "outDir": "./dist",
    "baseUrl": "./",
    "incremental": true,
    "skipLibCheck": true,
    "strictNullChecks": true,
    "forceConsistentCasingInFileNames": true,
    "noImplicitAny": false,
    "strictBindCallApply": false,
    "noFallthroughCasesInSwitch": false,
  }
}
{
  "compilerOptions": {
    "module": "nodenext",
    "moduleResolution": "nodenext",
    "esModuleInterop": true,
    "isolatedModules": true,
    "declaration": true,
    "removeComments": true,

    "outDir": "./dist",
    "baseUrl": "./",
    "incremental": true,
    "skipLibCheck": true,

    "forceConsistentCasingInFileNames": true,
    "noImplicitAny": false,
    "strictBindCallApply": false,
    "noFallthroughCasesInSwitch": false,
  }
}
Whenever I switch my module to esnext all the imports no longer are working

ArkType only supports ESM, which is supported by modern runtimes including node, even from CJS. You could try enabling "type": "module" in your package.json or just upgrading your runtime to a newer version of Node.

you're not a moron! that stuff has plagued the ecosystem for years hopefully soon with new versions being installed that support it by default it will be less and less frequent to run into that stuff, but always happy to help however I can!
