I’m just a beginner but it happens when you are passing the wrong URL to the fetch function, suppose that your db.json file is running on port 8000 and you are passing port 3000, that’s why.
useFetch(“http://localhost:3000/blogs/” + id);
Instead, try this, it might helps. 🙂
useFetch(“http://localhost:8000/blogs/” + id);
Hope it helps.
