If I add a build variable to a configuration, set it's value to "${request.isScheduled() ? true : false}" as I had in QB 2.x, then when I try to run the build I immediately get:

Failed to evaluate below expression: mvel:request.isScheduled() ? true : false

And the exception I see is:

Root cause:

[Error: unable to access property (null parent): isScheduled]
[Near : {... Unknown ....}]
