Error updating xml on WPBMap::addAllMappedShortcodes

Hello,
We manage a web with an old version of visualComposer (4.2 i think), the thing is the plugin starts failing on August 1st, debugging the code i found de problem in the line 1400 of class-woo-feed-products.php file, you are checking if WPBMap exists, in this case exists, but in our version the method “addAllMappedShortcodes” doesn’t exists. Can you add an method_exists(‘WPBMap’, ‘addAllMappedShortcodes’) condition to avoid this problem, please.
Thank you.
