When deploying all of our org's components and running all tests (Using a Force.com Migration Tool target invoked from Jenkins), we receive the following fatal deployment error:
UNKNOWN_EXCEPTION: A Definition of type 'EVENT' can not be added to this bundle.
There doesn't seem to be any indication of what component/file is causing this error, which makes it difficult to troubleshoot.
My guess is that this is somehow referring to a Lightning event in an aura definition bundle. We have around 30 aura components that all appear to be working correctly in our sandbox. 6 of those components are Lightning Events.
Any insight into what this error means (or how to start troubleshooting it) would be helpful.
