Variable Product Case : Fatal Error

Hello,
First thanks for this really great product.
Since I make the last update, I alway have a Fatal Error in my log,
PHP Fatal error: Uncaught Error: Call to undefined method WP_Error::get_data() in /home/admin/web/myWebsite.com/public_html/wp-content/plugins/woocommerce-pos/includes/apiv2/class-wc-pos-products.php:154

I tried to see what happen and it happens when POS tried to get variable product.
Here is a part of your code :

public function product_response( $response, $product, $request ) {
		$data = $response->get_data();
		$type = isset( $data['type'] ) ? $data['type'] : '';

		if ( $type == 'variable' ) :
			// nested variations
			foreach ( $data['variations'] as &$variation ) :

				if ( version_compare( WC()->version, '3.7', '<' ) ) {
					$response = WC()->api->WC_REST_Product_Variations_Controller->get_item(
						array(
							'id'         => $variation,
							'product_id' => $variation
						)
					);
				} else {
					$variation_controller = new WC_REST_Product_Variations_Controller();
					$response             = $variation_controller->get_item(
						array(
							'id'         => $variation,
							'product_id' => $variation
						)
					);
				}
				$variation = $response->get_data();
			endforeach;
		endif;
...

In a conditionnal for new woocommerce version you call function get_item() which doesn’t exist for WC_REST_Product_Variations_Controller.
And you want to add into it a class objet.

$response             = $variation_controller->get_item(
						array(
							'id'         => $variation, (Variation is not numeric here and you want to add it to 'id'
							'product_id' => $variation
						)
					);

And when I Print out WP_Error message, I got
ID non valide.

Hope you can check it in next release.
Thank you
