Insane that I can't comment because of lack of reputation. I just wanted to make a comment to say that you spelled auth wrong in your answer. You wrote "aithToken". I can't blame you because I didn't notice either and I just spent an hour trying to troubleshoot why it wasn't working, then I noticed that. Friendly FYI to anyone else who comes across this.
_aithToken=fake ---> _authToken=fake
