I’ve upgraded to GooglePlayGamesPlugin-0.11.01 and modified my code to request a token by calling **PlayGamesPlatform.Instance.RequestServerSideAccess** instead of  
**PlayGamesPlatform.Instance.GetUserId()** which is deprecated.

However, this token is not being accepted by **AuthenticateGoogleAsync**.

The following is logged by the server:

`{"level":"info","ts":"2022-09-23T17:20:29.337Z","caller":"server/core_authenticate.go:630","msg":"Could not authenticate Google profile.","error":"google id token invalid"}`

I have upgraded the client library to 3.5.0 and the server to Nakama 3.13.1+2000e4b8 but the error persists.

Is this an incompatibility and do I need to revert to Google Play 0.10.x?

Thanks.

Hi, we are not aware of that incompatibility at the moment.  
If you can, please open an issue/pull request for this error you’re facing.

Hi,

we are also trying to use Unity 2021.3.20 together with GooglePlayGamesPlugin-0.11.01 and have encountered the same issue as Dave.

Digging around a bit I found that in 0.10.14 the google API had a method called GetIdToken which is now replaced by RequestServerSideAccess. This new method also returns a string but this is not a jwt token like the previous method returned. So if I call AuthenticateGoogleAsync and pass the string from RequestServerSideAccess it’s failing because it’s not a valid jwt token.

The documentation here gives some more information about the changes needed on the server to convert this Server Auth Code to a Token which can then be used: [Enabling Server-Side Access to Google Play Games Services &nbsp;|&nbsp; Google Developers](https://developers.google.com/games/services/android/offline-access#exchange_the_server_auth_code_for_an_access_token_on_the_server)

The last message mentioned opening a issue. Do you know if there is something open already?

Thanks  
Andre
