bamboo.resultsUrl variable does not work

Also, I am finding that URL resolved from "bamboo.resultsUrl" is something like this: https://<my server>/bamboo/browse/viewDeploymentResult.action?deploymentResultId=18874369. Following that URL results in an "Internal Server Error" with message:

There is no Action mapped for namespace /browse and action name viewDeploymentResult.
