Exception while singing in

[AboulEinein]

Describe the bug
I'm getting an exception when trying to sign in using username and password.
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
In file AWSMobileClientExtensions.swift line 190

Here's the content of my awsconfiguration.json

    "UserAgent": "aws-amplify/cli",
    "Version": "0.1.0",
    "IdentityManager": {
        "Default": {}
    },

        "Default": {
            "PoolId": "POOL_ID",
            "AppClientId": "CLIENT_ID",
            "AppClientSecret": "SECRET",
            "Region": "REGION"
        }
    },
    "Auth": {
        "Default": {}
    }
}
