Your tsconfig.json

{
  "compilerOptions": {
    "target": "esnext",
    "module": "nodenext",
    "lib": ["dom", "es6", "esnext", "esnext.asynciterable"],
    "skipLibCheck": true,
    "sourceMap": true,
    "outDir": "./dist",
    "moduleResolution": "nodenext",
   ...
 }

You are missing "moduleResolution": "nodenext"
