Regarding Lab 16.3
When running the validate.js I get the message "AssertionError [ERR_ASSERTION]: error case should be tested". I believe my test routine works for success, digits !=4 and value not a Buffer so I am not sure what is being tested for that I am failing to capture. I purposefully don't want any code help, therefore I would appreciate a confirmation that I should keep looking!. I have the latest Jan 5 labs. Thanks.
