Cannot invoke method getNodeName() on null object

I am executing simple groovy script using scriptler jenkins plugin.

import hudson.model.Computer
import hudson.model.Node

println Computer.currentComputer().getNodeName()

If I execute this on master or any slave, giving me NullPointerException

java.lang.NullPointerException: Cannot invoke method getNodeName() on null object
        at org.codehaus.groovy.runtime.NullObject.invokeMethod(NullObject.java:77)
        at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:45)

java.lang.NullPointerException: Cannot invoke method getNodeName() on null object means for Computer.currentComputer().getNodeName() that Computer.currentComputer() returns null. As of why that is? There is not enough information to answer this
