| Description |

I upgraded from 2.1.8 to 2.1.10 and migrated the data.
In a master step, I have the following Node Match Condition that works fine in 2.1.8: node.getAttribute("os").startsWith("osx") && node.isAgent() In 2.1.10, I get this error: 20:41:16,885 ERROR - Build is failed. com.pmease.quickbuild.QuickbuildException: Failed to evaluate below expression: mvel:node.getAttribute("os").startsWith("osx") && node.isAgent() at com.pmease.quickbuild.util.ExceptionUtils.wrapException(ExceptionUtils.java:90) at com.pmease.quickbuild.DefaultExpressionManager.evaluate(DefaultExpressionManager.java:101) at com.pmease.quickbuild.stepsupport.StepJob.matches(StepJob.java:46) at com.pmease.quickbuild.grid.GridMatchTask.getJobGrid(GridMatchTask.java:111) at com.pmease.quickbuild.grid.GridMatchTask.map(GridMatchTask.java:72) at com.pmease.quickbuild.grid.GridImpl.execute(GridImpl.java:51) at com.pmease.quickbuild.DefaultBuildEngine.run(DefaultBuildEngine.java:434) at com.pmease.quickbuild.DefaultBuildEngine.access$1(DefaultBuildEngine.java:390) at com.pmease.quickbuild.DefaultBuildEngine$3.run(DefaultBuildEngine.java:804) at java.lang.Thread.run(Thread.java:619) Caused by: [Error: cannot invoke method: getAttribute] [Near : {...

| This is because the attribute "os" is not defined in one of your agents. |

| This is the view on my agent. As I said, it's the same agent as defined previously in 2.1.8, but doesn't work in 2.1.10. |

| This attribute needs to be defined on every agent since QuickBuild will call this expression against all agents. |
