Error during setup phase

I had tried resetting option various times…but it didn’t worked… What may be the possible cause?

This is an expected error. Its from the test that is failing. Perhaps you haven’t added the breakpoint correctly for debugger to stop. You need to do that in order to complete the TODOs and move forward with the next milestone.

The task of the milestone is to generate a list that is in the expected portion of the error.

Yeah so you need to complete your code accordingly to generate that list. Expected portion is from the test which contains the values that your code is supposed to return.

Then how do I perform next step??

Follow the TODOs. Complete the code.

Debugger is ignoring the breakpoint.
Any hints??

Make sure breakpoint is not on an empty line. It should be in at return statement of the method.
