    When I try the create invoice example i get the following errors:

    Notice: Trying to get property ‘params’ of non-object in /var/www/html/wp-includes/IXR/class-IXR-client.php on line 155

    Notice: Trying to access array offset on value of type null in /var/www/html/wp-includes/IXR/class-IXR-client.php on line 155

    The example is on the documentation here:
    https://wp-invoice.github.io/docs/api/#gsc.tab=0

    I am attempting to use the XMLRPC to create an invoice. I modified it a little to get it to work from a test page:

    <?php 
    
    //include_once( '../class-IXR.php' );
    //include_once( '../class-wp-http-ixr-client.php' );
    
    //Load WordPress 
      include_once( '../wp-load.php' );
      include_once( '../wp-includes/class-IXR.php' );
      include_once( '../wp-includes/class-wp-http-ixr-client.php' );
    
    $client = new WP_HTTP_IXR_Client( 'https://{SITE}/xmlrpc.php' );
    
    $client->query('wp.invoice', array(
      $method = 'create_invoice',
      $credentials = array('xmlrpc-user', 'password'),
      $args = array(
          'subject'     => 'Test API Invoice',
          'description' => 'Invoice descriptive information.',
          'type'        => 'invoice',
          'user_data'   => array(
              'user_email' => 'recipient@email.com',
              'first_name' => 'John',
              'last_name'  => 'Smith'
          ),
          'deposit'     => 15.99,
          'due_date'    => array(
              'month' => '09',
              'day'   => '10',
              'year'  => '2013'
          ),
          'currency'    => 'USD',
          'tax'         => 10.5,
          'tax_method'  => 'after_discount',
          'status'      => 'active',
          'discount'  => array(
              'name'   => 'Your Discount',
              'type'   => 'amount',
              'amount' => 1.20
          ),
          'items' => array(
              array(
                  'name' => 'Test item 1',
                  'description' => 'Item 1 description',
                  'quantity' => 2,
                  'price' => 2.65,
                  'tax_rate' => 1 //global 'tax' will be used in order to priority
              ),
              array(
                  'name' => 'Test item 2',
                  'description' => 'Item 2 description',
                  'quantity' => 4,
                  'price' => 3.85
              )
          ),
          'charges' => array(
              array(
                  'name' => 'Fee 1',
                  'amount' => 0.56
              ),
              array(
                  'name' => 'Fee 2',
                  'amount' => 0.99,
                  'tax' => 15 //global 'tax' will be used in order to priority
              )
          )
      )
    ));
    
    $new_invoice = $client->getResponse();
    ?>
