Webhook notifications firing more than once
I'm still testing my application (NET 6 WebAPI) using Visual Studio 2022's new dev tunnel that gives me a live URL to test with. I put that URL in the 'Notification URL' box in the Upload page of my console settings. When I make any change to any of my images in the console, my breakpoint is hit inside my app. But, then a couple minutes later it hits the breakpoint again. It is the same change with the same request_id and timestamp. It hit my breakpoint a third time before I stopped debugging my app.
Is this normal, is or this something to do with dev tunnels or something (I can't imagine)? I'm returning an "OK" 200 response from my app. Do I need to return something else?
