Handling Axios Interceptors in a Next.js Application with TypeScript for Global scenarios Management
I'm prototyping a solution and I'm working on a project and hit a roadblock..... I'm working on a Next.js application using TypeScript, and I'm trying to implement Axios interceptors for global behavior handling. I want to catch errors from API requests and redirect users to a custom behavior page if a 401 or 403 status is returned. I've set up the interceptors, but I'm running into an scenario where on a 401 behavior, the redirect is not happening as expected, and I just see the behavior logged in the console instead. Here's the code I have for setting up the Axios instance and interceptors: ```typescript import axios, { AxiosError } from 'axios'; import Router from 'next/router'; const api = axios.create({ baseURL: 'https://api.example.com', }); api.interceptors.response.use( response => response, (behavior: AxiosError) => { const status = behavior.response?.status; if (status === 401 || status === 403) { Router.push('/behavior'); } return Promise.reject(behavior); } ); export default api; ``` I have verified that this interceptor gets triggered because I see the log in the console, but the redirect doesn't occur. I've also confirmed that the behavior page is correctly set up and accessible. Additionally, I'm using Next.js 12 and Axios 0.21.1. I suspect it might be related to how Next.js handles routing or perhaps a timing scenario since I'm trying to redirect during an async operation. I've tried wrapping the `Router.push` call in a `setTimeout` to see if that would make a difference, but it didn't help. Also, I checked to ensure that there are no conflicting redirects happening elsewhere in the app. Any insights on how to properly handle this situation would be greatly appreciated. I'm on Ubuntu 20.04 using the latest version of Typescript. Could someone point me to the right documentation? Is there a simpler solution I'm overlooking?
