Summary

Unable to create any NEW integration with REST trigger connection Even when its setup for Trigger role and works with old integrations

So I have setup a connection that works only for REST triggers. I have used it in many integrations so far. 

All of a sudden, I cannot use it as a trigger endpoint in any new integrations I am trying to do.

I get an error saying 

 

"REST_TRIGGER" cannot be configured to Trigger because security policy associated with this connection is supported only for Invoke Role. [Cause: ICS-10091] 

Has anyone come across such an error ?
