Java.lang.NullPointerException error when adding Sandbox Tester in iTunes Connect
问题 I keep getting the Java.lang.NullPointerException error when trying to add a new user to the Sandbox Tester list in Users and Roles within iTunes Connect. I had just deleted all the testers in that list and was trying to start from scratch with new testers, emails and passwords. None had been used before. Is this an error on the Apple server side? Should I just try again tomorrow? 回答1: Not just you unfortunately. It seems like their servers are down at the moment - I'd say try again tomorrow.
