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.
回答2:
Does your password have an uppercase letter, lowercase letter and number? Looks like their password validation handler is messed up. I just submitted a bug report about it.
I was having the same problem for days until I figured this out.
