Hi Team, Can you please  help me how to fix below NullPointerException.

Moduel:TestNG And Data Driven Framework - LIVE PROJECT

Test case getting failed when i use below code for skipping Tests.

if(!DataUtil.isRunnable(testCaseName, xls)||data.get("Runmode").equals("N")){
test.log(LogStatus.SKIP, "Skipping the test as runmode is N");
throw new SkipException("Skipping the test as runmode is N");
}

Error:

java.lang.NullPointerException

Note:

it works good for skipping only test data 

if(data.get("Runmode").equals("N")){
test.log(LogStatus.SKIP, "Skipping the test as runmode is N");
throw new SkipException("Skipping the test as runmode is N");
}
