I am experimenting Webhooks as part of Sandbox Testing with App Store. In the Event Details page I see the entry for the Webhook trigger but it always ends in Failure.
Also, I am unable to send the test event from the Dashboard. It says not possible to connect.
The endpoint configured is tested separately, but not sure why I am experiencing this as part of the trigger or the test event. Unable to find any traces to debug this more.
Attaching the screenshot for reference.
Any help is greatly appreciated.
