Cannot call LoginWithFacebook on device via Unity without error

Hello. I'm just trying to get started with PlayFab on Unity. I have done some testing in the editor and things are working fine. However, on my iOS device I cannot call LoginWithFacebook without an error. I am logged into Facebook itself ok.

My app id is 197F.

I get error code 'Unknown'.

HttpCode: 200.

HttpStatus: Client failed to parse response from server.

No error details.

And this for the error message:

System.MemberAccessException: Cannot create an instance of PlayFab.Internal.ResultContainer`1[TResultType] because Type.ContainsGenericParameters is true.

So that everyone has the final info on this thread: This issue was fixed as of the July Unity SDK update, which was promoted to https://github.com/PlayFab/UnitySDK after we completed the Beta period.

Hey Andy,

This issue occurs when trying to build using the Mono2x build settings. This is a bad practice and will not pass Apple certification. Please use IL2CPP build settings when building from Unity to any iOS platform.

Let us know if this resolves your issue.

Happy to see that updating to 160725 fixes the issue and I can now build with Mono2x Scripting Backend.

You should remove the 'Best Answer' tag from this post because it's not.

Hi Zac.

Bad practice? Do you think every single build I do is for an Apple submission? The vast majority of builds I do are for development and Mono is much quicker. When compared to Mono, IL2CPP builds take at least double the time in Unity, and maybe 4 times as long to build in Xcode. For development I want a quick build.

I found this in your release notes here.

Known Issue (not resolved): SimpleJson does not serialize correctly when using the Player Setting "Scritping Backend" option: "Mono2x". Until this is fixed, please use "IL2CPP" if possible.

This tells me that the problem will be fixed. When can we expect that?

Hey Andy,

The issue is already "fixed" in the sense that we have refactored our Unity SDK to allow for developers to override the default serialization library. We will be releasing a guide on how to do this in the next week or so.

The root of the issue comes down to us not finding any one serialization library that properly works across all Unity build targets. So the only way to move forward is to allow developers to switch out libraries depending on the build target. So in this case, the developer will need to have another serialization library ready to use in place of SimpleJson.

If you are looking to move forward on using your own serializer let me know and I can walk you through the details.

I use JSON .NET which works across the platforms we build for. Please explain the details.

Zac Bragg Deactivated answered Apr 28, '16

Sure thing,

Essentially you need to:

Implement a wrapper (using PlayFab.ISerializer) to the serialization library of your choosing.
Assign the instance to PlayFab.SimpleJson.Instance before making any PF calls (Awake() or Start() works well for this)

Here is an example project where we have already created the serializer override for JSON.net. Let me know if you have any questions.

Sorry for not having this out in a more public fashion; thanks again for your patience,

I still get the same error with the overridden JSON handling when running on MONO.

I added the implementation from your sample and made sure the instance was set. I debugged it on the device and it does hit the overridden handlers.

Why haven't you used Unity's built-in #defines to make sure your code can handle the various build targets? There are ENABLE_MONO and ENABLE_IL2CPP which you could use to provide the appropriate Json handling that worked?

Any idea of when this will be fixed. I'm getting sick of long build times just to test.
