AWSS3TransferManager - Terminating app due to uncaught exception - objective-c

Question

I am creating a cordova plugin to upload images to s3.
When I build the project I get the following error:
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 have followed other answers on here and added the extra keys to the info.plist:

This is the function in the plugin.
- (void)uploadImage:(CDVInvokedUrlCommand*)command
{
AWSS3TransferManager *transferManager = [AWSS3TransferManager defaultS3TransferManager];
NSString* filePath = [command argumentAtIndex:0 withDefault:nil];
NSURL *uploadingFileURL = [NSURL fileURLWithPath: filePath];
AWSS3TransferManagerUploadRequest *uploadRequest = [AWSS3TransferManagerUploadRequest new];
uploadRequest.bucket = #"my-test-bucket";
uploadRequest.key = #"mykey";
uploadRequest.body = uploadingFileURL;
[[transferManager upload:uploadRequest] continueWithExecutor:[AWSExecutor mainThreadExecutor]
withBlock:^id(AWSTask *task) {
if (task.error) {
if ([task.error.domain isEqualToString:AWSS3TransferManagerErrorDomain]) {
switch (task.error.code) {
case AWSS3TransferManagerErrorCancelled:
case AWSS3TransferManagerErrorPaused:
break;
default:
NSLog(#"Error: %#", task.error);
break;
}
} else {
// Unknown error.
NSLog(#"Error: %#", task.error);
}
}
if (task.result) {
AWSS3TransferManagerUploadOutput *uploadOutput = task.result;
// The file uploaded successfully.
}
return nil;
}];
}
The exception is thrown at line:
AWSS3TransferManager *transferManager = [AWSS3TransferManager defaultS3TransferManager];

I found a solution using the answer provided in https://stackoverflow.com/a/39957439/3191747
Adding the following to didFinishLaunchingWithOptions in the AppDelegate solved the problem:
AWSStaticCredentialsProvider *credentialsProvider = [[AWSStaticCredentialsProvider alloc] initWithAccessKey:AWS_ACCESS_KEY secretKey:AWS_SECRET_KEY];
AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionAPSoutheast1
credentialsProvider:credentialsProvider];
AWSServiceManager.defaultServiceManager.defaultServiceConfiguration = configuration;
