We made a call to our APIM endpoint from postman. Somehow the request was failing and was giving 500 error along with an activityid in response.
Actually what was happening when we tested from APIM test console was that the request was timing out and never reaching the backend via application gateway.
We could NOT find any logs in application insights using the activity id received in postman. Can any confirm who is adding activity id in the response and why we could not find any logs in application insights?
