    I had the same problem. Did you include a return statement? For me, it stemmed from not understanding how the testing is done. I had included a print statement to print the results. When I changed it to a RETURN statement, the error went away. The instructions say to write a program, but really, you're only writing a function and stopping there. Adding more will make the testing setup error out.
