Doesn't work with simple TS package.

I've just created a simple package to share types across my monorepo and I'm getting an crazy error from ember-auto-import regarding the webpack. I'm using "ember-auto-import": "^2.2.3"

My simple package, have these two files:

// feature-flag.ts
export enum FeatureFlags {
  COMMERCE = 'COMMERCE'
}

// index.ts
export * from './feature-flag'

{
  "private": true,
  "name": "@peek-types/entities",
  "description": "Public type definitions and utilities concerning peek business domain.",
  "license": "UNLICENSED",
  "author": "Michael Villander <michael.villander@peek.com>",
  "version": "0.0.0",
  "scripts": {
    "lint": "yarn lint:js && yarn lint:types",
    "lint:js": "eslint --ext ts,js .",
    "lint:ts:fix": "eslint . --ext .ts,.js --fix",
    "lint:types": "tsc --skipLibCheck --noEmit"
  },
  "devDependencies": {
    "@typescript-eslint/eslint-plugin": "^5.3.0",
    "@typescript-eslint/parser": "^5.3.0",
    "eslint-config-standard": "^16.0.3",
    "eslint-config-standard-ts": "^21.0.0",
    "ts-standard": "^10.0.0",
    "eslint": "^7.32.0",
    "typescript": "^4.4.4"
  },
  "keywords": [
    "access:public"
  ],
  "engines": {
    "node": "12.* || 14.* || >= 16"
  }
}

And after I install this package on my Ember app I'm getting this error. and import it inside one component:

import { FeatureFlags } from '@peek-types/entities'
