[V5] Need help configuring CORS for my app

[furatamasensei]

I saw a cors config file but I don't see where it was applied. How do I configure it?
Where should I apply it? Is it applied automatically when I changed any properties inside it?

I can't get my app works because of this.

Access to XMLHttpRequest at 'http://localhost:3333/api/v1/personalInfo/3126' from origin 'http://localhost:8100' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Here's what I've tried so far:

1. Changed the origin: true to Env.get('STATEFUL_DOMAINS') ?? true in cors.ts
2. Added PATCH request inside the methods: [...] in cors.ts
3. Added STATEFUL_DOMAINS=[ 'http://localhost', 'http://localhost:3333', 'http://localhost:8100' ] on the .env file
4. Restart the server.

I'm a little bit confused by this because the app was perfectly fine when I accessed it via Postman

I removed that Env.get('STATEFUL_DOMAINS') ?? true and hardcoded to this:

origin: [
  'http://localhost',
  'http://localhost:3333',
  'http://localhost:8100',
],

Works fine now.
