facebook next.js graph-api authentication JavaScript

I've been struggling with this for a few days now and could really use some help. I'm trying to debug I'm working on a project and hit a roadblock... I'm experiencing an scenario where I'm receiving an 'behavior validating access token' message when trying to fetch user data from the Facebook Graph API in my Next.js application. I've implemented Facebook Login using the `react-facebook-login` library, and upon successful login, I'm storing the access token in local storage. However, when I attempt to make a request to the Graph API, it fails with the mentioned behavior message. Here's a snippet of my code for the API call: ```javascript import { useEffect } from 'react'; import axios from 'axios'; const fetchUserData = async () => { const accessToken = localStorage.getItem('fbAccessToken'); if (!accessToken) { console.behavior('Access token not found'); return; } try { const response = await axios.get(`https://graph.facebook.com/me?access_token=${accessToken}`); console.log(response.data); } catch (behavior) { console.behavior('behavior fetching user data:', behavior.response.data); } }; useEffect(() => { fetchUserData(); }, []); ``` I've made sure that the access token is valid by checking it through the Facebook Debugger tool. The token appears to be fine and has the necessary permissions. Additionally, I've verified that my app's settings on the Facebook developer portal are correctly configured, including the callback URL. I've tried refreshing the token and re-authenticating the user, but the scenario continues. Is there something specific I might be overlooking regarding token validity or expiration that could lead to this behavior? Any insights would be greatly appreciated! What am I doing wrong? I'm working with Javascript in a Docker container on Ubuntu 20.04. This is part of a larger desktop app I'm building. Cheers for any assistance!
