Unable to see run time Groovy script errors in Virtualize

We are using SOATest & Virtualize 9.13 version. The issue is...we are not able to see run time Groovy script errors in Virtualize console logs.
for example in the below method If I am referring the undeclared/undefined variable script is failing silently and not able to figure out where its showing the run time error.
public void GenerateError(Object input, ExtensionToolContext context) {
fsdfsdf;
}

Note: The same script when run in SOATest, its showing the error in Quality Tasks.
