WC Add to cart with Ajax - Only first product is added

Question

I have WordPress 5.6.1 + WooCommerce 4.9.2

I created a function to add product into cart with Ajax. My function is very specific as I create a new tailored product and then added to cart.

First I had issue to authorize this ajax call for non connected users. This is corrected but now I have issue :

First product is correctly added to cart
Next products are not added to cart (but created correctly)

Can you have a look on my code?

I force Ajax Call otherwise not working for non connected users

function forceAjaxCall(){
  function forceit(){
      if(isset($_REQUEST['action']) && $_REQUEST['action']=='create_product_sdwc'):
              do_action( 'wp_ajax_' . $_REQUEST['action'] );
              do_action( 'wp_ajax_nopriv_' . $_REQUEST['action'] );
      endif;
  }
  add_action('wp_loaded', 'forceit');
}

My ajax function

function odc_create_product_sdwc() {  
 ob_start();
 global $woocommerce;
 $product = new WC_Product();
 $d = new DateTime();
 $product->set_props( array(
     'name'               => "Produit test",
     'featured'           => false,
     'catalog_visibility' => 'hidden',
     'description'        => "ma Description",
     'short_description'  => 'Transparence : ',
     'regular_price'      => 10,
     'sale_price'         => 10,
     [....]
 ) );

 $productId = $product->save();

 $passed_validation = apply_filters( 'woocommerce_add_to_cart_validation', true, $productId, 1 );
 error_log("passed_validation " . $passed_validation);

 $reponse = $woocommerce->cart->add_to_cart($productId, 1);
 error_log("added to cart : key " . $reponse);
 error_log("added to cart : ID " . $productId);
 do_action( 'woocommerce_ajax_added_to_cart', $productId );

 wp_die();

}

I noticed that if I remove wp_die() then the product is created 4 times. I think my issue is about cache or ob_start, flush etc but can't find a solution.. — Olivia

After hours or research I finally found the solution... The add_to_cart was correct

The issue was with the non logged users and my function forceAjaxCall()

Correct answer is :

function forceAjaxCall(){
    function forceit(){
        if(isset($_REQUEST['action']) && $_REQUEST['action']=='create_product_sdwc'){
            do_action( 'wp_ajax_nopriv_' . $_REQUEST['action'] );
        };
    }
    add_action('admin_init', 'forceit'); // admin_init !!!!
}
