TOO_MANY_REDIRECT - How to track the culprit?

Hello guys. Mostly from nowhere, or at least nowhere I can look at, I end up having 407 redirection when loading my app. I'm not able to identify the culprit, and was wondering which will be the best path to track and understand the root cause. Any tips, inspect flag or something I can use to understand what nitro is doing under the hood? #nitro #redirect #debug

Hi @kogratte. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To track and debug the issue of too many redirects in your Nuxt application, here are some tips and approaches you can try: 1. Use the --inspect flag when running your Nuxt app in development mode. This allows you to use Node.js debugging tools to inspect what's happening under the hood. You can run:

   nuxi dev --inspect

   nuxi dev --inspect

This will start Nuxt in dev mode with the debugger active, allowing you to attach to it using Chrome DevTools Debugging with Node Inspector (https://nuxt.com/docs/guide/going-further/debugging#debugging-with-node-inspector). 2. Enable source maps in your Nuxt configuration. This can help with debugging by providing more accurate stack traces:

   export default defineNuxtConfig({
     sourcemap: {
       server: true,
       client: true
     }
   })

   export default defineNuxtConfig({
     sourcemap: {
       server: true,
       client: true
     }
   })

Sourcemaps (https://nuxt.com/docs/guide/going-further/debugging#sourcemaps) 3. Check your middleware, especially any global middleware (*.global.ts). Infinite redirects often occur due to incorrect logic in navigation guards. Make sure you're not always returning a new location within a navigation guard Stack Overflow - Nuxt 3 middleware infinite navigation guard (https://stackoverflow.com/questions/77271028). 4. Review your routeRules in the Nuxt configuration. Incorrect route rules can sometimes cause redirect loops Github Issue Comment (https://github.com/nuxt/nuxt/issues/29108). 5. If you're using an IDE like VS Code or JetBrains IDEs, set up a debug configuration to step through your code. This can help identify where the redirects are occurring Example VS Code Debug Configuration (https://nuxt.com/docs/guide/going-further/debugging#example-vs-code-debug-configuration). 6. Check for any issues with your authentication logic if you're using auth in your app. Incorrect handling of authenticated/unauthenticated states can lead to redirect loops. 7. Use the Nuxt DevTools (if not already enabled) to inspect your app's behavior:

   export default defineNuxtConfig({
     devtools: { enabled: true }
   })

   export default defineNuxtConfig({
     devtools: { enabled: true }
   })

Nuxt DevTools (https://nuxt.com/docs/guide/going-further/debugging#sourcemaps) 8. If the issue persists and you can't identify the cause, consider creating a minimal reproduction of the problem and seeking help from the Nuxt community Reporting Bugs (https://nuxt.com/docs/community/reporting-bugs). Remember, when debugging redirect issues, it's crucial to carefully review your middleware, navigation guards, and any code that might be triggering route changes. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I ran my solution with the --inspect flag. Whats should I look for? I don't have a clue about any redirection. I need to set a breakpoint, but where?

Let me check the knowledge base for you again. One moment! :books: ---------------------- When using the --inspect flag with your Nuxt application, you're on the right track for debugging your redirection issue. Here's what you should look for and where to set breakpoints: 1. First, make sure you've attached to the Node.js debugger. When you run nuxi dev --inspect, you should see a message in your console with a URL to open in Chrome Debugging with Node Inspector (https://nuxt.com/docs/guide/going-further/debugging#debugging-with-node-inspector). 2. Once connected, you'll want to set breakpoints in areas that could potentially cause redirects. Here are some key places to consider: a. Middleware files: Look for any .ts or .js files in your middleware directory, especially any global middleware files (ending with .global.ts). Set breakpoints at the beginning of these middleware functions. b. Navigation guards: If you have any navigation guards in your pages or layouts, set breakpoints there. c. Plugin files: Check your plugins directory for any plugins that might be interfering with routing. d. nuxt.config.ts: If you have any routeRules defined, set a breakpoint there. 3. In the Chrome DevTools, navigate to the "Sources" tab and look for your project files. You may need to use the file navigator to find the relevant files. 4. Set breakpoints by clicking on the line numbers in these files where you suspect redirects might be happening. 5. Refresh your application and watch for where the execution stops. This will help you trace the flow of your application and identify where redirects are occurring. 6. Pay special attention to any logic that checks authentication status or uses navigateTo() or similar routing functions. If you're still unsure where to start, you can set a breakpoint at the entry point of your application (often in the app.vue file) and step through the code execution from there. Remember, debugging can be an iterative process. You might need to set and remove breakpoints in different locations as you narrow down the source of the problem. If you're new to debugging with Chrome DevTools and Node.js, you might find it helpful to review the VS Code debugging configuration for Nuxt (https://nuxt.com/docs/guide/going-further/debugging#example-vs-code-debug-configuration), which can provide a more integrated debugging experience if you're using VS Code. Lastly, if you're still struggling to identify the cause, consider creating a minimal reproduction of the issue and seeking help from the Nuxt community, as suggested in the Reporting Bugs (https://nuxt.com/docs/community/reporting-bugs) documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Do you have any middleware? Are you navigating conditionally anywhere? These are often hot spots

It was due to looping deps. I though yarn was smart enough to manage them, but it does not seems to be the case. Nb:never change your package management on a release day 🤣
