Hello!
I'm unable to create subscriptions for a Custom Topic in Event Grid. I'm trying to use Webhook as my endpoint type. I'm also using the Event Grid Schema.
I'm getting the following error:
Deployment has failed with the following error: {"code":"Url validation","message":"Webhook validation handshake failed for https://fapp-testo.azurewebsites.net/api/HttpTrigger1. Http POST request failed with response code Unknown. Activity id:9f95a3a1-0574-417c-bf0a-53488457347a, timestamp: 10/7/2020 8:59:16 PM (UTC)."}
For troublehooting, visit https://aka.ms/esvalidation.
I have enabled System Assigned Identity
I also enabled system assigned identity for dead-lettering
Sometimes it works and I'm able to see the subscription listed within my Custom Topic, But after a few seconds it goes away.
What I´m trying to achieve is from my application call my Custom Event Grid Topic so it can trigger some HTTPS Azure Function I have, (this as webhooks).
Please help.
Thank you
