### What happened?
While trying to map Test Suite with Test Case the migration is stopped and getting the error as Object reference not set to an instance of an object again in the next run the error test case is mapping and getting the same error for the next test case.

1. Is this consttant for teh same test case?
2. Can you debug to "AddChildTestCases" and see if all of the values passed to the API have a value?
