Facebook-sdk-for-unity: Facebook SDK v7.16.0 NullReferenceExceptions on iOS

[renattou]

After installing v7.16.0, the SDK throws an error almost every time I interact with it (for example when calling FB.LogInWithReadPermissions).

The error is as follows:

System.NullReferenceException: Object reference not set to an instance of an object.
  at Facebook.Unity.CodelessUIInteractEvent.Update () [0x00000] in <00000000000000000000000000000000>:0 
UnityEngine.DebugLogHandler:Internal_Log(LogType, String, Object)
UnityEngine.DebugLogHandler:LogFormat(LogType, Object, String, Object[])
UnityEngine.Logger:Log(LogType, Object)
UnityEngine.Debug:Log(Object)
Facebook.Unity.CodelessUIInteractEvent:Update()

(Filename: ./Runtime/Export/Debug.bindings.h Line: 45)

I'm using Unity 2018.4.0f1, Xcode 10.1, iOS 12.3.1 and .NET 4.x.

I found this was happening when I upgraded to 7.16.0 from 7.15.1. I discovered that the issue seemed to related to the fact by upgrading and not doing a clean install of the SDK, some previous files were left over causing all sorts of conflicts. I suggest deleting the FacebookSDK folder and the PlayServicesResolver, and then reinstalling 7.16.0.

I'm having the same NullReferenceException on Android 9 using Unity 2018.3.10f1. I did try completely deleting the FacebookSDK folder before importing version 7.16.0

@EmpTim I already tried on a clean project and I still had this problem :/

We have this too. Clean install. It seems not to be an unhandled exception but simply a log message from Facebook SDK internals. Does anyone know whether v7.16.0 still functions or not?

We have clean install of v7.16.0 too. The same issue. This error occurs in Editor, Android, and iOS.

Same issue here, Does it have any consequence on analytics logs ? I have to wait 24 hours before seeing any log to know if it has any impact.

Same issue. please solve this problem

[Albob]

Same here. I can see it in the editor, haven't tried iOS or Android.
I did a semi-clean install: removed all FB files, but kept the PlayServicesResolver files.

[KylinChang]

The issue is fixed in v7.16.1

I'm getting this issue in FB 7.17.0.
I've noticed that the Facebook SDK creates an EventSystem if one is not found, but my app manages it's own event systems. And if I delete the one that FB creates, then I get this error.
Can you just make the code try to find an existing event system if the one it has is deleted?

Thanks :)

Still have this issue in 7.17.1

Same issue as VoxelMatt and kodekq, I'm also using fb unity 7.17.1 with error log
