Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /Users/michal/dev/test/node_modules/typescript-functional-extensions/dist/index.js
require() of ES modules is not supported.
require() of /Users/michal/dev/test/node_modules/typescript-functional-extensions/dist/index.js from /Users/michal/dev/test/dist/app.service.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/michal/dev/test/node_modules/typescript-functional-extensions/package.json.
