Module-24 - Rediff Test-video number 20-Implementation of Portfolio Test

I am working on Implementing Rediff test using Hybrid framework.

Part1 - Creation of base Hybrid framework was successful.

Part2 - Rediff test , having issue in Implementing the 'PortfolioTest'(Video -20)

I modified my dataprovider under 'baseClass'as shown below. After modifying, none of my test cases are executing. When i revert the getData() method..it starts running again. Please advise.

@DataProvider
public Object[][] getData(Method method){
// i can use xls file object to read data
//System.out.println("Inside data Provider "+method.getName());
testName=method.getName();
return DataUtil.getTestData(testName, xls);
}

Error message:

FAILED: loginTest
org.testng.TestNGException:
