I am using user pools with my iOS mobile app.
I would like to access my lambda functions using the sdk but can't find documentation on how to provide the authentication necessary. Also unclear as to whether I need to use the API Gateway if I am using the sdk with user pools.
I am using this method to access my lambda function:
private func invokeLambda(data: [String: Any]) {
let appDelegate = UIApplication.shared.delegate as! AppDelegate
let pool = appDelegate.pool
let credentialsProvider = AWSCognitoCredentialsProvider(regionType: .USEast1, identityPoolId: "MyIdentityPoolId", identityProviderManager:pool)
let configuration = AWSServiceConfiguration(region:.USEast1, credentialsProvider:credentialsProvider)
AWSServiceManager.default().defaultServiceConfiguration = configuration
let lambdaInvoker = AWSLambdaInvoker.default()
let jsonObject: [String: Any] = data
lambdaInvoker.invokeFunction("myFunction", jsonObject: jsonObject).continueWith(block: {(task:AWSTask<AnyObject>) -> Any? in
if let error = task.error as NSError? {
if (error.domain == AWSLambdaInvokerErrorDomain) && (AWSLambdaInvokerErrorType.functionError == AWSLambdaInvokerErrorType(rawValue: error.code)) {
print("Function error: \(error.userInfo[AWSLambdaInvokerFunctionErrorKey])")
} else {
print("Error: \(error)")
}
return nil
}
// Handle response in task.result
if let JSONDictionary = task.result as? NSDictionary {
print("Result: \(JSONDictionary)")
print("resultKey: \(JSONDictionary["resultKey"])")
}
return nil
})
}
I am getting the following error:
"AccessDeniedException"
Edit #1
The error that I am getting indicates the unauth role is being used for access rather than the auth role. the user is correctly logged in and the token is valid. Not sure where I am going wrong here.
