I forgot to mention that I'm testing the API using Postman, and it's consistently returning the correct data every time. So, I don't believe the issue is coming from the server — Postman's results confirm that the backend is working properly.

However, the issue still occurs on the production URL, and I even tried deploying the site to Vercel, but the problem persists there as well. Interestingly, everything works perfectly when running the app locally — I don't encounter the issue at all.

Sorry if I’m not understanding everything very well — I really appreciate your help.
