Steps to create a remote event receiver
RER is getting deployed successfully but not getting triggered. I tried to debug it but I am getting below message
One or more services were unregistered from the Microsoft Azure Service Bus. Cannot register Services/AppEventReceiver.svc on Microsoft Azure Service Bus: The remote server returned an error: (500) Internal Server Error.
I looked for the message and getting solution related to Connection string only. I have tried creating Service Bus from Azure UI and using Powershell both, but still not able to debug the solution.
Any ideas?
