I'm working on a project that checks an email list that is imported to see if the user is registered or not on yahoo.
When I click on the Start button, it should go to the yahoo mail sign up page and check every email on this imported txt file. I've relied on htmlunit library but it always gives an exception, despite disabling the JavaScript and ThrowExceptionOnScriptError
this the exceptions always happens
