Skip trigger if failed because dependent job was canceled

[mattymo]

The plugin is triggering even when {status} is set to canceled, but I only have "Trigger when build is failed" set. My build log for the job that triggers slack is:

This build has not been started because some of the builds it depends on were canceled
[19:46:23]
Snapshot dependency "... 2.3 - Build A docker image" canceled
[19:46:23]
Snapshot dependency "... 2.4 - Build B docker image" canceled
[19:46:23]
Build finished

How can I suppress this slack message trigger?
