Using the .NET CDK,

var inputQueue = new Queue(this, "InputQueue", null);
var inputProcessor = new QueueProcessingFargateService(this, "InputProcessor", new QueueProcessingFargateServiceProps
            {
                Cluster = cluster,
                Image = ContainerImage.FromAsset("./NetInfluencersProcessorOutput", null),
                Queue = inputQueue
            });

results in the following error:

Unhandled Exception: Amazon.JSII.Runtime.JsiiException: System.Reflection.TargetParameterCountException: Parameter count mismatch.

Removing the Queue argument resolves the exception.

• What is the expected behavior (or behavior of feature suggested)?
  I should be able to specify a queue construct to use.

• What is the motivation / use case for changing the behavior or adding this feature?
  It's a bug. Documentation says this should work.

• Please tell us about your environment:

  • CDK CLI Version: 1.3.0 (build bba9914)
  • Module Version: 1.3.0-devpreview
  • OS: Windows 10
  • Language: .NET (Not tested with Typescript)

@eladb, @NGL321 looks like this might be related to JSII and not to the ECS construct itself. The following in typescript works:

const vpc = new ec2.Vpc(stack, 'MyVpc', { maxAzs: 2 });
const cluster = new ecs.Cluster(stack, 'Cluster', { vpc });
const queue = new Queue(stack, 'queue', {});

new ecs_patterns.QueueProcessingFargateService(stack, "FargateService", {
  cluster,
  image: ecs.ContainerImage.fromAsset(path.resolve(__dirname, 'local-image')),
  queue,
});

Yeah this is clearly a JSII issue. This may have been fixed in the latest jsii, we should try to reproduce again once a version of CDK ships with jsii >= 0.15.1

Relates #2375
Relates aws/jsii#404

Same root cause, Correctly deserialize callback arguments #404

Might be fixed in the next CDK release!

[RomainMuller]

Confirmed fixed in CDK >= 1.18.0.
