HostedUI SignIn failure

[YarinShitrit]

I am following the docs for implementing the Auth and Cognito into my android application and I am facing an error when trying to signin through facebook with hostedUI.
Here is the logcat error :

AuthException{message=Sign in with web UI failed, cause=java.lang.Exception: showSignIn called with HostedUI options in awsconfiguration.json, recoverySuggestion=See attached exception for more details}

my LoginFragment code :

facebook_login_btn.setOnClickListener {
            Log.d(TAG, "Facebook Login Clicked")
            Amplify.Auth.signInWithSocialWebUI(
                facebook(),
                requireActivity(),
                { result -> Log.i("AuthQuickstart", result.toString()) },
                { error -> Log.e("AuthQuickstart", error.toString()) }
            )

}

Any suggestions ?
Thanks

Hi @YarinShitrit based on your configuration files, it looks like you haven't configured an OAuth flow, which is required for HostedUI. When you run amplify add auth, choose Default configuration with Social Provider (Federation).

Your amplifyconfiguration.json should have an OAuth object. It should look something like this:

{
    "UserAgent": "aws-amplify-cli/2.0",
    "Version": "1.0",
    "auth": {
        "plugins": {
            "awsCognitoAuthPlugin": {
                "UserAgent": "aws-amplify-cli/0.1.0",
                "Version": "0.1.0",
                "IdentityManager": {
                    "Default": {}
                },
                "CredentialsProvider": {
                    "CognitoIdentity": {
                        "Default": {
                            "PoolId": "us-east-1:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
                            "Region": "us-east-1"
                        }
                    }
                },
                "CognitoUserPool": {
                    "Default": {
                        "PoolId": "us-east-1_xxxxxxxxxx",
                        "AppClientId": "xxxxxxxxxxxxxxxxxxxxxxxxxxx",
                        "AppClientSecret": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
                        "Region": "us-east-1"
                    }
                },
                "Auth": {
                    "Default": {
                        "OAuth": {

                            "AppClientId": "xxxxxxxxxxxxxxxxxxxxxxxxxxx",
                            "AppClientSecret": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
                            "SignInRedirectURI": "myapp://callback/",
                            "SignOutRedirectURI": "myapp://signout/",
                            "Scopes": [
                                "phone",
                                "email",

                                "aws.cognito.signin.user.admin"
                            ]
                        },
                        "authenticationFlowType": "USER_SRP_AUTH"
                    }
                }
            }
        }
    }
