Laravel 500 Internal Server Error

A generic server-side error indicating something went wrong during request processing.

Explanation

The 500 Internal Server Error is Laravel's catch-all error when an unhandled exception occurs. It typically means a bug exists in your application code, a misconfigured environment, or a server-level issue. The actual error details are logged in storage/logs/laravel.log. In production, this error shows a generic page to users for security. The underlying cause could be anything from a missing configuration value to a database connection failure.

Common Causes

  • Unhandled exception in application code
  • Missing or incorrect environment variables
  • Database connection failure
  • Misconfigured middleware
  • Missing PHP extension

Solution

Check the Laravel log file at storage/logs/laravel.log for the specific exception message. Ensure APP_DEBUG=true in your .env file during development to see detailed error pages. Verify that all required environment variables are set correctly in the .env file. Clear configuration and route caches with php artisan config:clear and php artisan route:clear. If the issue persists, check server error logs (nginx, apache) for PHP-level errors.

Code Example 

// In a controller, this unhandled exception causes a 500:
public function getUser($id)
{
    // If the database is down, this throws an unhandled exception
    $user = DB::table('users')->find($id);
    return $user;
}

// Fix: wrap in try-catch and handle gracefully
public function getUser($id)
{
    try {
        $user = DB::table('users')->find($id);
        if (!$user) {
            return response()->json(['error' => 'User not found'], 404);
        }
        return $user;
    } catch (Exception $e) {
        Log::error('Failed to fetch user: ' . $e->getMessage());
        return response()->json(['error' => 'Server error'], 500);
    }
}
