Update your route with

use App\Http\Controllers\aController;

Route::get('/getmsg', [aController::class, 'index']);

Laravel 8 requires you to provide a complete path to the controller or you can define a default namespace to locate your controllers like this, define following in your RouteServiceProvider.php

protected $namespace = 'App\Http\Controllers';

You should get a response from the controller.

Firstly check if you are using jquery-3.2.1.slim.min.js, slim version are not supported so remove slim version and replace it with:

<script
  src="https://code.jquery.com/jquery-3.6.0.min.js"
  integrity="sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4="
  crossorigin="anonymous"
></script>

then after if library link is correct check for things like csrf, route, data etc.
