Xcode NullReferenceException ERROR but ONLY on iPad, not on iPhone

Unity Engine
1

I’ve been developing a game for iphone and ipad. 95% of the test on iphone but every once in a while I will test on ipad as well. It’s worked fine on ipad until now. The current version of game builds and runs fine on iphone but I get an error (and freeze) when trying to build and run on ipad. I do not know how to find out where this null ref exception is originated so I am reaching out for help.

ERROR:
NullReferenceException: Object reference not set to an instance of an object.

It seems to be something to do with Facebook SDK since that is the area code it was at most recently as the log indicates…

in testFBfetch set FBloggedIN = true
now assigning aToken = facebook.unity.accesstoken.currentaccesstoken next
after assigning aToken = facebook.unity.accesstoken.currentaccesstoken next
NullReferenceException: Object reference not set to an instance of an object.

If I click the yellow caution icon and look at the last reported item in Xcode it shows this… (not positive this is related but perhaps?)

FBSDKURL *parsedUrl = [FBSDKURL URLWithInboundURL:url sourceApplication:nil]; (THEN ERROR… NULL PASSED TO A CALLEE THAT REQUIRES A NON NULL ARGUMENT

(screenshot attached)

Any help would be appreciated!

If you’re using the Facebook SDK, you’ll need to make sure that you get a proper access token for your game from Facebook. Are you actually using Facebook for your game?

Yes, using Facebook SDK to get user ID and for sharing, etc. This all works on iPhone… I can log in as FB user, etc. On iPad it hangs at launch with that NullReferenceException

Actually it is also giving that error on my wife’s iphone. My iphone is working fine. So not ipad/iphone related but something else. How do I trace back where the nullreferenceexception is coming from?

If you sign into any social media apps (I forget the list) on Apple, you MUST also implement “Sign In With Apple”

Not sure this is the technical reason it is failing, but perhaps Apple has begun to roll out a technical crosscheck.
