Amplify-ios: Error configuring AmplifyPlugins.AWSCognitoAuthPlugin after updating Amplify to 1.0.2

[AboulEinein]

Describe the bug
After updating Amplify to 1.0.2 I started getting the following error

AuthError: Error configuring AmplifyPlugins.AWSCognitoAuthPlugin
Recovery suggestion: Could not read Cognito identity pool information from the configuration. Make sure that auth category
is properly configured and auth information are present in the configuration. You can use Amplify CLI to
configure the auth category.
  ▿ configuration : 3 elements
    - .0 : "Error configuring AmplifyPlugins.AWSCognitoAuthPlugin"
    - .1 : "Could not read Cognito identity pool information from the configuration. Make sure that auth category\nis properly configured and auth information are present in the configuration. You can use Amplify CLI to\nconfigure the auth category."
    - .2 : nil

Here's the content of my awsconfiguration.json

            "Region": "REGION"
        }
    },
    "Auth": {
        "Default": {
            "authenticationFlowType": "USER_SRP_AUTH"
        }
    }
}

amplifyconfiguration.json

                "IdentityManager": {
                    "Default": {}
                },
                "CognitoUserPool": {
                    "Default": {

                        "AppClientSecret": "SECRET",
                        "Region": "REGION"
                    }
                },
                "Auth": {
                    "Default": {
                        "authenticationFlowType": "USER_SRP_AUTH"
                    }

@palpatim @royjit while the configuration error seems to be fixed, I'm facing another issue while signing in.
The signIn function receives nil when retrieving the user from the user pool, which results in Thread 12: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0) exception
AWSMobileClientExtensions.swift line 190

@AboulEinein
I tried to do a username password sign in and it worked without any issue. Few things to clarify:

1. Do you have any initializing / configuring call to AWSMobileClient
2. Which Amplify signIn api caused this error?
3. Your amplifyConfiguration.json remains the same as shown above?
4. Do you have any initializing / configuring call to AWSInfo

@royjit

1- Amplify is configured as following in the AppDelegate

do {
    try Amplify.add(plugin: AWSCognitoAuthPlugin())
    try Amplify.configure()
    print("Amplify configured with auth plugin")
} catch {
    print("Failed to initialize Amplify with \(error)")
}

2- public func signIn(username: String? = nil, password: String? = nil, options: AuthSignInOperation.Request.Options? = nil, listener: AuthSignInOperation.ResultListener?) -> AuthSignInOperation
3- Yes, the configuration is the same.
4- No

@royjit any updates?

Can we open this as a new issue so we can track it appropriately?
