I am trying to call a backend service via cloud connector and destination in BTP. The call is successful while running from Business Application Studio(BAS) but after deploying to CF and running from Launchpad workzone, the service call is returning HTTP 403 Forbidden error.
Try to see if the password of your destination was cleared after deployment. Or check whats value is in existing_destinations_policy in your app. Try to change it to ignore like here: existing_destinations_policy: ignore.
