Laravel With inertiajs-react get 419 Error (Page expired) when trying to update a record.

When working with Laravel and InertiaJS-React, you might encounter a 419 Error (Page expired) when trying to update a record. This error typically occurs when there is a conflict between the data you are trying to submit and the current data in the database.

Here are some steps you can take to troubleshoot and resolve this issue:

Check for CSRF Token Mismatch: Laravel uses CSRF protection to prevent unauthorized requests. Ensure that you have included the CSRF token in your InertiaJS-React request. You can check this by inspecting the network tab in your browser's developer tools and verifying that the CSRF token is present in the request headers.
Check for Concurrent Transactions: If two or more requests are trying to update the same record at the same time, it can result in a conflict and a 419 error. You can prevent this by using Laravel's optimistic locking feature. This feature allows you to update a record only if no other transaction has modified it since you last fetched it.

To enable optimistic locking, you need to add a version column to your database table and update your Laravel model to use it. Here's an example:

// app/Models/User.php

protected $versionField = 'version';

// database/migrations/xxxx_xx_xx_add_version_to_users_table.php

Schema::table('users', function (Blueprint $table) {
    $table->integer('version')->default(0);
});

Check for Expired Session: If your session has expired, you might get a 419 error. You can check if your session has expired by logging out and then trying to update the record again. If the issue persists, you might need to increase the session timeout value in your Laravel configuration file.

// config/session.php

'lifetime' => 120, // in minutes

Check for Network Issues: If you are experiencing network issues, it might cause a 419 error. You can check your network connection by trying to access other websites or running network diagnostics tools.
Check for Server Timeout: If your server is taking too long to process the request, it might result in a 419 error. You can check your Laravel configuration file for the queue timeout value and increase it if necessary.

// config/queue.php

'connections' => [
    'database' => [
        'queue' => 'default',
        'retry_after' => 90, // in seconds
    ],
],

By following these steps, you should be able to resolve the 419 error when trying to update a record in Laravel with InertiaJS-React.
