swift 3 awslambda invoker error [duplicate] - ios

Question

I am facing a strange issue with AWSS3.
Setup:
AWS Mobile HUB
Cognito
DynamoDB
S3
--> Cognito, Dynamo & even S3 (through cognito user data) work.
However I now tried to connect directly to AWS3 with the following code:"
let transferManager = AWSS3TransferManager.default()
let uploadRequest = AWSS3TransferManagerUploadRequest()
uploadRequest?.bucket = "XXXXXXXXXXXX"
uploadRequest?.key = "user-data/" + awsId! + "/primary_profile_picture.png"
uploadRequest?.body = imgUrl as URL
transferManager.upload(uploadRequest!).continueWith(executor: AWSExecutor.mainThread(), block: { (task:AWSTask<AnyObject>) -> Any? in
if let error = task.error as? NSError {
if error.domain == AWSS3TransferManagerErrorDomain, let code = AWSS3TransferManagerErrorType(rawValue: error.code) {
switch code {
case .cancelled, .paused:
break
default:
print("Error uploading: \(uploadRequest?.key) Error: \(error)")
}
} else {
print("Error uploading: \(uploadRequest?.key) Error: \(error)")
}
return nil
}
let uploadOutput = task.result
print("Upload complete for: \(uploadRequest?.key)")
return nil
})
and am getting the error:
AWSiOSSDK v2.5.1 [Debug] AWSInfo.m line:122 | -[AWSServiceInfo initWithInfoDictionary:checkRegion:] | Couldn't read the region configuration from Info.plist for the client. Please check your `Info.plist` if you are providing the SDK configuration values through `Info.plist`.
2017-02-20 19:29:21.748997 [2210:1152801] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'The service configuration is `nil`. You need to configure `Info.plist` or set `defaultServiceConfiguration` before using this method.'
I am using the downloaded plist configuration from AWS Mobiel HUB and am therfore a bit surprised that it does not work (as all other components do).
Any ideas what the issue might be? The plist actually contains the bucket ID & region.

Answer 1

For me, I had to configure the credentials with the following code, before uploading:
let credentialsProvider = AWSCognitoCredentialsProvider(regionType:.USEast1,identityPoolId:PoolID)
let configuration = AWSServiceConfiguration(region:.USEast1, credentialsProvider:credentialsProvider)
AWSServiceManager.default().defaultServiceConfiguration = configuration
Where PoolID is my Cognito identity. I hope this helps others.

Answer 2

Your info.plist needs to have S3TransferManager in it.
So, **AWS -> S3TransferManager -> Default -> Region -> ...**
You can find an example of one here

Answer 3

Swift 3 - Xcode 8.3.3
For people still having this issue, I just spent 3h fighting against this annoying setup issue.
I added both these chunks in my Info.plist (replace the variables between ** ** in the second bloc) and now it's working again.
Amazon's documentation isn't updated properly I think. I hope this can save some people some time.

Answer 4

I had the same issue instead of S3TransferManager you should put DynamoDBObjectMapper
e.g..
<key>DynamoDBObjectMapper</key>
<dict>
<key>Default</key>
<dict>
<key>Region</key>
<string>us-east-1</string>
</dict>
</dict>

Answer 5

The problem was, region should be:
us-east-1
Instead of; US_EAST_1

Answer 6

Add Service configuration file with the data
If the above marked solution is not working for some cases. Try the below solution.
As the error says, the service configuration file is nil. So, we need to add the awsconfiguration.json file with the below data.
{
"Version": "1.0",
"IdentityManager": {
"Default": {}
},
"CredentialsProvider": {
"CognitoIdentity": {
"Default": {
"PoolId": "REPLACE_ME",
"Region": "REPLACE_ME"
}
}
},
"S3TransferUtility": {
"Default": {
"Bucket": "REPLACE_ME",
"Region": "REPLACE_ME"
}
}
}
Replace the bucket, region, poolId of your project.
