wc_get_product_id_by_sku not working anymore

I’m working on a script that retrieves an external CSV file and then processes that into the database. I need the function wc_get_product_id_by_sku to get the product ID.

Everything worked when using this steps:

Retrieve the file with CURL
Process a few things
Use the function wc_get_product_id_by_sku()
But, since I wanted to use the WordPress function wp_remote_request(), I get the following Error:

Fatal error: Uncaught Error: Call to undefined function wc_get_product_id_by_sku() in /sites/..
Everything else remains the same and works!

Do these functions interfere with each other? How is it possible that it works one way, but not the other way around?

$response = wp_remote_request( $host );

        $result = wp_remote_retrieve_body($response);

        if(empty($result)) {
            exit;
        }           

        // Default: CSV has a top row
        $toprow = true;

        // Get settings for the CSV fields
        $sku = get_option('blabla_sku');

        // Parse CSV into array
        $rows = array_map('str_getcsv', explode("\n", $result));
        if($toprow)
        {
            $header = array_shift($rows);
            $products = array();
            foreach ($rows as $row) {
              $products[] = array_combine($header, $row);
            }
        }
        else { $products = $rows; }

        foreach($products as $product) {

                if(wc_get_product_id_by_sku($product[$sku]) !== 0) {
                    // Do something
                }

            }
