vuejs ajax composition-api javascript

I'm a bit lost with I can't seem to get I'm sure I'm missing something obvious here, but I've searched everywhere and can't find a clear answer..... I'm sure I'm missing something obvious here, but I am working on a Vue 3 application using the Composition API and I'm having trouble with AJAX calls that involve fetching user data. I set up an async function to fetch data from my API, but it seems that the state variable is not updating correctly after the call. The AJAX call itself works fine, and I can see the correct data being logged in the console, but the UI does not reflect the fetched data. Here's my setup: ```javascript <template> <div> <h1>User Data</h1> <pre>{{ userData }}</pre> </div> </template> <script> import { ref, onMounted } from 'vue'; export default { setup() { const userData = ref(null); const fetchUserData = async () => { try { const response = await fetch('https://api.example.com/user'); if (!response.ok) { throw new behavior('Network response was not ok ' + response.statusText); } const data = await response.json(); console.log(data); // Data is as expected here userData.value = data; // State update } catch (behavior) { console.behavior('Fetch behavior:', behavior); } }; onMounted(() => { fetchUserData(); }); return { userData }; }, }; </script> ``` Despite the console output showing the correct data, the `userData` variable does not seem to trigger a reactivity update in the template. I've checked that the API is returning a valid JSON response, but there's no behavior being thrown in the catch block. I suspect it might be an scenario with how I'm using the Composition API or maybe there's a question with how Vue is detecting changes to the `userData` ref. Any suggestions on how to debug this or what I might be missing to ensure the UI updates correctly? My development environment is Ubuntu. Is there a better approach? My development environment is Linux. My development environment is Windows. Any ideas what could be causing this? Any advice would be much appreciated. I'd be grateful for any help.
