iOS authentication is failing in latest version

[josephnarai]

This was working fine, but coming back to retest now (after all the new features), the iOS authentication is failing now.

Failed to execute authorization procedure. Check application settings and credentials.

We tried changing to 4.6 scripting - but that breaks the entire app on iOS and downloads stop working on Android :(

Please advise how best to debug and fix this?

Joe

[elringus]

Which Unity version are you using? Also, please try to change the loopback URI (in the GoogleDriveSettings asset) to http://127.0.0.1 (don't forget to also whitelist it in the console app) and add plist based on this message: https://forum.unity.com/threads/google-drive-sdk-for-unity-free-open-sourced.515360/#post-3426567

[elringus]

And just to be sure, before trying the above, check if the auth credentials in the GoogleDriveSettings are correct (try to parse them again from the json) and delete cached auth tokens in the build via GoogleDriveSettings.DeleteCachedAuthTokens().

[josephnarai]

running 2017.4.1 Unity

[josephnarai]

With regard to the auth credentials, it's working on PC and Android just fine ... do you still suggest I delete the cached Auth Tokens?

We have completely uninstalled the App from the device - this then forces a reauthorisation... and are still getting the issue.

We shall try the whitelist and plist settings as you suggest and let you know.

[elringus]

One more question: you've mentioned that you've tried running under 4.6 backend and that caused other issues, but was the auth working at the same time?

[josephnarai]

It was still working on PC and Android, but on iOS all touch stopped working, so we could not test it at all :(

[elringus]

I've modified the loopback provider so it'll work async even on .NET 2.0. Can you please check whether that has any effect on the issue?

[josephnarai]

great - will try it out and let you know! Thanks.

[elringus]

Transfer you mean upload/download? I've only changed the loopback auth flow, nothing else. If the auth is working fine now, we probably should close this issue.

[josephnarai]

I don't have the iOS system here. I'm waiting for my partner to test. I will advise as soon as I know if the issue is resolved - but I didn't see this crash until I updated to this new version.

[elringus]

Looks like it's a Unity internal nullef issue happening here: https://github.com/Elringus/UnityGoogleDrive/blob/master/Assets/UnityGoogleDrive/Runtime/GoogleDriveRequest.cs#L219

WebRequest is not null when starting the send operation (could it be you're reusing the same request instance?), so we're attempting to abort and dispose it, but the pointer to actual request instance seems to be not valid on the C++ side.

[elringus]

I've made a change to explicitly null the WebRequest on completion. Maybe this will help to prevent the issue.

[josephnarai]

I tried downloading the package - but it's saying there are no changed? Does the package need to be rebuilt?

[elringus]

One file has changed. I've linked the commit summary in the previous message.

[elringus]

Oh, are you downloading the unity packages from the releases page? I'm not changing those. Please directly pull the repository to get the latest changes.

[josephnarai]

Ah - ok I thought you were updating the package - seems to have worked previously!

[josephnarai]

I didn't clone the repo - thought I could just download the zip and copy the files out - but the file structure in the zip seems to be very different to the repo? I'm confused, can I not just download the zip of the repo?

[josephnarai]

nevermind - I tried downloading the zip again and it worked as expected

[elringus]

In the zip you'll get the entire Unity project. You can just extract the Assets/UnityGoogleDrive folder to get only the essential files, that are bundled with the released packages.

[josephnarai]

I've done that. So far the null reference exception has not reoccurred :)

It's 11pm here in Sydney, so my partner won't get a chance to test with iOS until tomorrow morning. I'll report back as soon as I have information.

Thanks again for the great support. Much appreciated.

[adamsingle]

I'm having a similar problem, except I have no errors. Authentication on the iPad just never switches applications to a browser. Everything is working on desktop. I've updated to the latest code. I've added the plist entries. I have 127.0.0.1 as the loopback uri and have it whitelisted in the app console. But I never see an error. It just looks like the process never gets to the point of kicking off the Application.OpenURL that should trigger the browser to come in. I'm completely stumped. We had it working about 2 days ago, but then good old mac forced a xcode/ios update on us and it all stopped. Any advice would be hugely appreciated

[adamsingle]

I tell a lie. There was an error showing up in xcode, but not in the Unity Log.

looks to be the same that josephnarai was/is seeing

[elringus]

@adamsingle just to make sure: you've tried the latest code from the repository (by pulling or downloading a zip), not from one of the packages downloaded via the releases page or readme?

[elringus]

And please specify which Unity version and .NET backend you're using. If it's possible, please try using .NET 4.6 and latest Unity version (2018.1 or 2018.2 beta).

[josephnarai]

I downloaded the zip - we are running in 2017.4 (can't go to 2018, it breaks other code for us) - we are testing iOS now

[adamsingle]

I'm using the latest code from the repo. I am using .NET 4.6. I can't use the latest version of Unity at this point however. We are using 2017.4f1. This project is for a client and we're on version lockdown unless I can make a strong case for upgrading. The issue is we have a process to retest a lot of functionality when we upgrade Unity versions. Is that likely to be an issue? Interesting that @josephnarai is using the same version as I am and having the issue too.

[josephnarai]

We are seeing the same result as adamsingle: 2018-06-07 16:30:43.739949+1000 cards[1397:929778] [BoringSSL] Function boringssl_session_errorlog: line 2881 [boringssl_session_read] SSL_ERROR_ZERO_RETURN(6): operation failed because the connection was cleanly shut down with a close_notify alert

we can NOT use 4.6 as it completely breaks touch input on iOS

[elringus]

Thanks for the info. One more question: you've mentioned a forced update, was it for the iOS 12?

[josephnarai]

So, I just checked, and XCode was udated for us on May 30 -- and we last tested our iOS implementation before then and it was working - so I would say it's likely that the update to Xcode has broken this.

Also, our current build does the same as adamsingle in that it no longer prompts the user at all... just a blank screen and that error in the log.

[josephnarai]

We could try 2018.1 - as a test, but if it's xcode related do you think that will help ?

[elringus]

Well, trying 2018.1 won't be absolutely useless, but chances are not high, I guess.

[josephnarai]

ok - is there anything else you would like us to try?

[elringus]

@josephnarai @adamsingle can you please provide the full logs of the ones you've posted earlier? The stuff about "BoringSSL" isn't actually useful, the real issue should be somewhere below that message.

[josephnarai]

There isn't any more!

[josephnarai]

That's the log when we try and initiate a download "StartSyncFiles Down: True" is the start

[elringus]

I think I've found the issue: a part of the auth request uri string could've been not escaped properly and looks like on some platforms that worked somehow, while iOS just silently fails when invoking Application.OpenUrl with a malformed uri. Please try the latest code (via a direct pull or downloading a zip).

[josephnarai]

Testing now

[josephnarai]

But it's no longer prompting to authenticate (after the first one)

[elringus]

Make sure you've set scripting backend to .NET 2.0 (not subset), the third party JSON library is not working with the subset, unfortunately.

[josephnarai]

Oh, we have had it set to subset always -- so is this iOS specific?

[elringus]

It affects only the AOT platforms, I believe.

[josephnarai]

switching "subset" off fixed it! I'm not sure what other impact that might have on the project - we shall do some more testing, but it appears we are working again!

Thanks!

[elringus]

.NET 2.0 subset is just, well, a subset of .NET 2.0 APIs used to reduce the build size. You'll win about 1-2 MB off the build size using it, but it will also strip a lot of APIs. So when you switch to the full profile, nothing could possibly break, you'll just get a slightly larger build.

[elringus]

I've published a new release with all the fixes. Feel free to reply to this issue in case something still won't work regarding the auth on iOS.

[mohsinkhan26]

This issue is still there and causing this issue!

Hi @Elringus, I am getting the same error as @mohsinkhan26:
