From yesterday I failed to validate the endpoint until now, the steps as below: 1. In [marketplace.zoom.us](http://marketplace.zoom.us/) page, click Developer in the top right → click Build Video SDK 2. Enable the Event subscription button, click Add Event Subscription, type the endpoint url, then click validate button, and then I got the error message “An error was encountered when processing your request” ![截屏2022-08-11 00.12.36](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/e/7/e7ff2850056e8b986d6a4d0965ca15ab772f8b42.jpeg) Could you please give me some suggestion? Thanks a lot. Leon ---
