AmazonCognitoSyncClient - UpdateRecordsAsync - Unhandled Exception - The requested feature is not implemented #21

Closed jasonmc86 closed 9 years ago

jasonmc86 commented 9 years ago

I'm trying to write a update record request in a Portable library for aws in xamarin and i get a not implemented exception.

Code:

Amazon.CognitoSync.AmazonCognitoSyncClient client = new AmazonCognitoSyncClient(AuthManager.TempCreds.AccessKey, AuthManager.TempCreds.SecretKey, RegionEndpoint.USEast1);

        var result = client.UpdateRecordsAsync(new UpdateRecordsRequest
        {
            DatasetName = "obj",
            IdentityId = AuthManager.CognitoCreds.GetCachedIdentityId(),
            IdentityPoolId = AuthManager.CognitoCreds.IdentityPoolId,
            RecordPatches = new List<RecordPatch>
            {
                new RecordPatch {
                    DeviceLastModifiedDate = DateTime.Now,
                    Key = Guid.NewGuid().ToString(),
                    Op = Operation.Replace,
                    SyncCount = 0,
                    Value = JsonConvert.SerializeObject(obj)
                }
            },
            SyncSessionToken = "",
        }).Result;

What am i doing wrong to get this stack trace?

@jasonmc86 Are you implementing this is in the PCL? Correct. The Xamarin SDK uses the Bait and Switch method for implementation http://log.paulbetts.org/the-bait-and-switch-pcl-trick/ in which the implementation will be executed on the specific platform.

jasonmc86 commented 9 years ago

@tawalke Yeah in the PCL. Do i need to implement it in the Platform specific projects? Why does the xamarin aws sdk use the bait and switch approach? is not possible to have a shared implementation? Could you demo up some code to show me what i'd need to do instead?

tawalke commented 9 years ago

Yes, create an interface in the PCL and implement the actual desired implementation in the platform you want to support.

Reference Paul Betts blog on Bait and Switch if you need more info: http://log.paulbetts.org/the-bait-and-switch-pcl-trick/ It's the best reference for usage of Bait and Switch.

jasonmc86 commented 9 years ago

Appreciate your help :+1: I've got a button click event in a xamarin list view, how do i tell xamarin to run the click event handler in each platform (that runs the code above), rather than the button click event I declare in the PCL?

Or rather even tell xamarin to run my an inteface's method in the platform specific code.

jasonmc86 commented 9 years ago

I'll play and let you know if I can't get it going. Thanks :p

tawalke commented 9 years ago

No worries, let me know how it goes. Another good reference point is: http://visualstudiomagazine.com/articles/2014/02/01/using-portable-class-libraries-in-ios-and-android-apps.aspx

tawalke commented 9 years ago

@jasonmc86 Your question about the click event, you use platform abstraction and create an interface that does it which will instantiate based upon the platform. Check out the Visual studio link I pasted above.

jasonmc86 commented 9 years ago

@tawalke I got the code to be called from the android project, but just hangs :-1:

using (AmazonCognitoSyncClient client = new AmazonCognitoSyncClient (awsUserCreds.AccessKey, awsUserCreds.SecretKey, awsUserCreds.Token, RegionEndpoint.USEast1)) { var datasets = client.ListDatasetsAsync(new ListDatasetsRequest{

                }).Result;

                var recordsResult = client.ListRecordsAsync (new ListRecordsRequest {
                    DatasetName = dataSetName,  
                }).Result;

                var result = client.UpdateRecordsAsync (new UpdateRecordsRequest {

All three just hang. :-1: any ideas?

tawalke commented 9 years ago

Hmm, let’s brainstorm here…You have set to correct IAM permissions right?

Yeah my IAM roles are correct if I do similar code call via node js aws SDK works fine

tawalke commented 9 years ago

Okay, I will write similar code and see what the issue is and replicate the problem.

@jasonmc86 Were you using the new v4 or previous v3?

jasonmc86 commented 9 years ago

I'm using the NuGet Package which i believe is still at 2.1.7 can you please update it... package id="AWS-Mobile-SDK-Xamarin-Beta" version="2.1.7" targetFramework="portable-net45+wp80+MonoAndroid10+xamarinios10+MonoTouch10"

tawalke commented 9 years ago

Once all testing is complete with the Xamarin.iOS folders for Unified API it will be updated.

jasonmc86 commented 9 years ago

@tawalke yes the same thing happens with the updated dll's from here. Ie v4

tawalke commented 9 years ago

@jasonmc86 For clarity:

When you call this code the below it hangs, are you calling await in the code or Task.Run for the Result. I only got a code snippet here, so I don't see where the async function is being executed by an calling an await or Task.Factory or Task.Run

using (AmazonCognitoSyncClient client = new AmazonCognitoSyncClient (awsUserCreds.AccessKey, awsUserCreds.SecretKey, awsUserCreds.Token, RegionEndpoint.USEast1)) { var datasets = client.ListDatasetsAsync(new ListDatasetsRequest{ }).Result;

            var recordsResult = client.ListRecordsAsync (new ListRecordsRequest {
                DatasetName = dataSetName,  
            }).Result;

            var result = client.UpdateRecordsAsync (new UpdateRecordsRequest
jasonmc86 commented 9 years ago

@tawalke It doesn't matter whether i use await or task.run .. both just never finish the task (ie it hangs) How do i debug the aws source code locally with xamarin studio?

var cognitoCredentials = Credentials as CognitoAWSCredentials; if (cognitoCredentials != null) {
string identityId = await cognitoCredentials.GetIdentityIdAsync(); SetIdentity(executionContext, identityId, cognitoCredentials.IdentityPoolId);
}

tawalke commented 9 years ago

That is indeed very odd. What platform are you writing on or are you using Xamarin.Forms?

I will have to create a quick client with CognitoSync to see if I get this error, which I haven’t before. So I want to keep the code as you have it and not my interpretation of it

So repeating/asking some things for clarity:

You are or are not passing Cognito Credentials (they are needed)

You are using await (or any PTL methodology) to kick off the request

You are writing classic Xamarin w/Android or Xamarin.Forms?

You are referencing the v4 compiled binary or you compiled the sdk

1 I create the cognito client using Amazon.CognitoSync.AmazonCognitoSyncClient client = new AmazonCognitoSyncClient(AuthManager.TempCreds.AccessKey, AuthManager.TempCreds.SecretKey, RegionEndpoint.USEast1);

tawalke commented 9 years ago

Okay, I will create a Xamarin.Forms portable project to test this scenario

which i believe creates session aws credientials not AWSCognito ones

I was using .Result (of the task) to wait for the result to come back without using await or task.run (although neither helped)

@tawalke i complied the code on my machine removing the custom CognitoCredentialsRetriever and it is all working now. Could you take a look at what is wrong with the custom handler... Ie Removing the following override in aws xamarin code and my code works fine.

    protected override void CustomizeRuntimePipeline(RuntimePipeline pipeline)
    {
        pipeline.RemoveHandler<Amazon.Runtime.Internal.CredentialsRetriever>();
        pipeline.AddHandlerBefore<Amazon.Runtime.Internal.Marshaller>(new Amazon.CognitoSync.Internal.CognitoCredentialsRetriever(this.Credentials));
    }

Thanks,

Jason

tawalke commented 9 years ago

Okay will do, I will test with both.

@findly-jasonmcmonagle Re-Copying what you have at the top, I'm assuming this is the same code; Going to start a new project and try to make this occur. Are you doing Xamarin.Forms PCL or Xamarin.Forms Shared Project

Hi:

This Beta SDK should now be migrated to use the AWS SDK for .NET with Xamarin has been released. As noted, this release is under AWS SDK for .NET and is in Developer Preview. The Xamarin SDK repo has the latest links for this update, as well as, the updates for the updated NuGet packages.

This should resolve you issue as this has the updated services and codebase desired. See links below: https://github.com/aws/aws-sdk-net https://github.com/aws/aws-sdk-net#nuget-packages
