CognitoUserSession is not valid because idToken is null.

[jbsolutions2008]

Hi all, we are trying to configure the Amplify Authentication on Android 12, but when we try to sign in the result callback is called with a signInState equal to SignInState.DONE, but when we try to get the token (both sync or async),

an Exception raises: "CognitoUserSession is not valid because idToken is null. "

To Reproduce
A code sample or steps:

 #1 After  SignInState.DONE : 
 -------------------------
  fun finishSignIn() {
        launch(Dispatchers.IO) {
            AWSMobileClient.getInstance().getTokens(object : Callback<Tokens> {
                override fun onResult(result: Tokens?) {
                    result?.let {
                        Logger.d("token ${it.accessToken}")
                        val token = AWSMobileClient.getInstance().tokens.accessToken.tokenString
                        Logger.d("token $token")
                    }
                }
                override fun onError(e: java.lang.Exception?) {
                    e?.let {
                      Logger.d("token $e.toString()")
                    }
                }
            })
        }
    }
 
#2 Retrive token null in the result   
-------------------------------------

@jbsolutions2008
Does your awsconfiguration.json file have a block like this?

{ 
  "CredentialsProvider": {
    "CognitoIdentity": {
      "Default": {
        "PoolId": "POOL-ID-HERE",
        "Region": "REGION-ID-HERE"
      }
    }
  }
}

Thank you for the update.
No, provided awsconfiguration.json is different from ours. We have shared our awsconfiguration.json file. Please review and update for the further process.

awsconfiguration.json

  "Version": "1.0",

hi @jbsolutions2008, I am currently looking into your issue. Could you verify that you sent awsconfiguration.json? The file you sent seems to be amplifyconfiguration.json. Please let me know if my assumption is incorrect.

Hello. I'm having this issue when try to verify if the user is signed in. I'm working in flutter. But it only happens the first time I enter after singout. It rise the exception then return true or false after a while. The exception take me to the login page again and the when try to login it works fine.. I'll put my code in a while...

[dengdan154]

Hi @Felixroldan, if you are still facing this issue, please paste your code here as well as the awsconfiguration.json and any reproduction steps and we can continue looking into this issue.

I guess upon registration is successful , you need to provide a CognitoUserSession so that we can get idToken , RefreshToken and so on ..
