Data Driven using excel

I am trying to write a data driven script to run multiple scenarios but I run into an error "FAILED because (of) java.lang.IllegalArgumentException:…". Previously I had written data driven scripts & they were working perfectly so I am not too sure what’s causing this error all of a sudden.

This is the line in my script where the error is throw: ExcelData Data = findTestData(‘PFI DD_Quick Capture_Add Insured_ErrorHandling’)

Did you find the solution. I am getting the same issue?
