 * We have started getting this error message when ever we try to checkout as of
   yesterday
    Error message: Fetch Error
 * order/
 * {“code”:”rest_invalid_param”,”message”:”Invalid parameter(s): meta_data, line_items”,”
   data”:{“status”:400,”params”:{“meta_data”:”meta_data[0][value] is not of type
   string,null.”,”line_items”:”line_items[0][meta_data][0][value] is not of type
   string,null.”}}}
 * I updated WP today to try and fix it with no luck.
 * Nothing changed on the site yesterday to make me think something else has caused
   this error, please help

 * Thanks for reaching out and reporting the bug to us. We are tracking this bug
   as an open issue related to the recent WooCommerce update to version 4.3.2 in
   the last 24 hours and we are working on a hotfix to release an update with a 
   point fix ASAP to address the issue.
 * In the meantime, we’d recommend you revert back to WooCommerce 4.3.1, you can
   download the previous WC version here from the WordPress.org listing, here: [https://wordpress.org/plugins/woocommerce/advanced/](https://wordpress.org/plugins/woocommerce/advanced/)
 * Please keep the POS updated, we should have a fix soon, so you can upgrade to
   version 4.3.2 of WooCommerce.

 * Good news, the WooCommerce version 4.3.2 inadvertently introduced an issue impacting
   the API. WooCommerce released a new point fix 4.3.3 to fix and restore the API
   compatibility, as announced on the blog today: [https://woocommerce.wordpress.com/2020/08/14/woocommerce-4-3-3-fix-release/](https://woocommerce.wordpress.com/2020/08/14/woocommerce-4-3-3-fix-release/)
 * Please go ahead and update WooCommerce to version 4.3.3, the update to WooCommerce
   will restore functionality to the POS plugin and resolve the issue reported for
   the Fetch Error.
 * We will continue to monitor the performance, if you encounter any new issues 
   after updating to WooCommerce 4.3.3, please reopen the support forum post or 
   create a new issue and report to us. Thank you
