javascript - Problem on wordpress i can't post data in ajax on wordpress plugin

Question

I am currently learning to use the wordpress CMS and I have a problem with the development of my plugin, I would need to send a data with the ajax post method, the problem is that the request is sent (status code 200, OK), but my targeted php page does not receive it .. Thank you in advance for your help =)

My code :

php file :

<?php 
/**
* Plugin Name: Covid Tracker
**/
if(!defined('ABSPATH')){
    define('ABSPATH', dirname(__FILE__) . '/');
}
include_once("db_CT.php");
register_activation_hook(__FILE__,"DBP_tb_create");
include_once("dataAdd.php");
register_activation_hook(__FILE__,"addDB");
add_shortcode('CoviT', 'CT');

function CT(){
    
    echo ("
        <div id='CT'>
        <input type='hidden' id='dir' value='".plugin_dir_url(__FILE__).'filter.php'."'>
        <input type='hidden' id='adminAjaxDir' value='".site_url().'/wp-admin/admin-ajax.php'."'>
        <input type='text' value='' id='search' placeholder='Search department'>
        <button id='submit' class='btn btn-primary'>Search</button>
            <table class='blueTable'>
                <thead>
                    <tr>
                        <th>Nom</th>
                        <th>Date</th>
                        <th>hospitalises</th>
                        <th>gueris</th>
                        <th>deces</th>
                        <th>nouvelles Hospitalisations</th>
                        <th>nouvelles Reanimations</th>
                        <th>reanimation</th>
                    </tr>
                </thead>
                
                <tbody id='tbody'>
                    
                </tbody>
            </table>
        </div>
    ");
    wp_enqueue_script('appCT', plugin_dir_url(__FILE__) . 'appCT.js');
    wp_enqueue_style('styleCT', plugin_dir_url(__FILE__) . 'styleCT.css');
    
    wp_enqueue_script( 'ajax', plugin_dir_url(__FILE__) . 'ajax.js');
    wp_localize_script( 'ajax', 'adminAjax', admin_url( 'admin-ajax.php' ) );
    
    
}


add_action('wp_ajax_nopriv_doAjax', 'get_data');
add_action('wp_ajax_doAjax', 'get_data');
    

function get_data(){
    if(isset($REQUEST)){
        $search = $REQUEST['value'];
        echo 'Hello';
    }
    die();
}

?>

ajax.js :

function sendSearch(){
    var search = document.getElementById('search').value;
    jQuery(document).ready(function($) {
        $.ajax({
            url: '/integrationWP/wp-admin/admin-ajax.php',
            method : 'POST',
            data:{

                'value': search
            },
            success: function(data){
                // alert('?a fonctionne !');
            },
            error: function(errorThrown){
                alert('error');
                console.log(errorThrown);
            }
        });
    });

                console.log(data);
                var total = data['allLiveFranceData'].length;
                for(var i = 0; i < total; i++){
                    var departement = data['allLiveFranceData'][i];
                    var name = departement['nom'];
                    var date = departement['date'];
