MongoDB Adapter, Listener Notification, ART.116.3139, EventType Definition doesnt exists in the EventTypeStore for notification

Hi folks,

What this message means? “ART.116.3139] Adapter Runtime (Notification): EventType Definition doesnt exists in the EventTypeStore for notification : <notification_name>.”

Product/components used and version/fix level:

Integration Server 10.11 w/ IS_10.11_WmCloud_Fix2 and IS_10.11_Core_Fix12
MongoDB Adapter for webMethods 9.12 w/ MAW_9.12_Fix3

Detailed explanation of the problem:

I’m trying enable ‘publish events’ on a Listener Notification, but it refuses from working.

The underlying MongoDB Adapter Connection is enabled, the “read preference” is “secondary” and “read concern” is on “majority”. The Listener Notification is enabled. The document type has been successfully synchronized with the Universal Messaging.

Error message (server.log)

(it is the same as mentioned in the beginning of this post.)

What is this “Event Type Store”? Isn’t it the same as the plain old doc types synchronized with the Universal Messaging for later publishing?
