This code has always worked until now. Now I have updated Woocomerce to the new version 9.0.1 and it no longer works.

I have the following error in the log:
woocommerce_deliver_webhook_async -> action failed via WP Cron: Call to a member function get_endpoint_data() on null

Maybe you can help me and update the code?
