WooCommerce: creating an order programmatically with a variable product

Question

I am trying to create an order programmatically. Using wc_create_order()it is pretty simple:

$myProduct = new WC_Product(100);
$order = wc_create_order();
$order->add_product($myProduct, 1);
$order->calculate_totals();

This works as expected and an order is created for a simple product with ID 100 for the correct amount.

However, if I try to do this with a change, it does not seem to behave correctly. After much trial and error, I got this to sort the work this way:

$membershipProduct = new WC_Product_Variable(100);
$theMemberships = $membershipProduct->get_available_variations();

$trueProduct = new WC_Product(100);

$variationsArray = array();

foreach ($theMemberships as $membership) {
    if ($membership['sku'] == $chosenVariation) {
        $variationID = $membership['variation_id'];
        $variationsArray = $membership['attributes'];
    }
}

if ($variationID) {
    $trueProduct->variation_id = $variationID;
}

$order = wc_create_order();
$order->add_product($trueProduct, 1, $variationsArray);
$order->calculate_totals();

However, although it creates an order with the correct product and the correct variation identifier, the amount for the order is always 0 (which, coincidentally, is the price of the first option).

:

$membershipProduct = new WC_Product_Variable(100);
$theMemberships = $membershipProduct->get_available_variations();

$variationsArray = array();

foreach ($theMemberships as $membership) {
    if ($membership['sku'] == $chosenVariation) {
        $variationID = $membership['variation_id'];
        $variationsArray['variation'] = $membership['attributes'];
    }
}

if ($variationID) {
    $varProduct = new WC_Product_Variation($variationID);

    $order = wc_create_order();
    $order->add_product($varProduct, 1, $variationsArray);
    $order->calculate_totals();
}

$args=array();
foreach($product_variation->get_variation_attributes() as $attribute=>$attribute_value){
