Thanks for those many useful extensions

when i use sendTypingEvents then broadcasting/auth is forbidden 403 showing.... why this is happened I couldn't find any solution of this please give me a solution
The 403 Forbidden error usually occurs when the user is not authenticated or authorized to join the private channel. To fix this, make sure that: 1. User is Authenticated: Ensure that the user is logged in before trying to join the private channel. 2. Channel Authorization: Check your `BroadcastServiceProvider` or the corresponding channel class to ensure proper authorization logic. For example: ```php Broadcast::channel('chat.{id}', function ($user, $id) { return (int) $user->id === (int) $id; }); ``` 3. Correct Middleware: Verify that you are using the correct middleware for broadcasting, such as `auth:api` or `auth:web`, depending on your setup. 4. CSRF Token: Ensure that the CSRF token is being passed correctly with your requests. I recommend watching the tutorial again to see how it's implemented step by step. Let me know if you need further assistance!

laravel reverb only for laravel 11 or availabel too in laraval 9?
No, Laravel Reverb does not support Laravel 9. You should upgrade to Laravel 11 Or you can use Laravel WebSockets. I have already created a detailed video on this. Here is the playlist URL: czcams.com/play/PL1TrjkMQ8UbWfFUCimQ50CdrR_J7QvEFW.html
Excuse me, I want to ask something, I'm stuck. Why is it that I can use Laravel's auth sanctum cookie locally but it doesn't work when deployed to development server? Error 401 when getting user after successfully logging in. Is there something missing in the sanctum config?
Sanctum cookie issues on deployment are common. Check cookie domain, CSRF, session config, and CORS. - Ensure SANCTUM_DOMAIN in your .env file is set correctly for both environments. - Check if your browser is blocking third-party cookies, which might affect cookie settings on the development server. - Verify that the CSRF token is handled correctly in your frontend. Make sure it's included in requests. - For API routes, you might need to exclude them from CSRF verification in app/Http/Middleware/VerifyCsrfToken.php. - Check your session configuration in config/session.php. Ensure it's consistent between environments. Pay attention to domain, path, and secure options. - If your frontend and backend are on different domains, CORS might be interfering. Configure CORS headers appropriately in your backend.
@@QiroLab Yes, my problem has been found because the session in Laravel was not called correctly.
