Incorrect template for cloudwatch dashboard #6746

DamirAinullin · 2020-03-16T16:27:13Z

I try to use CDK to create AWS monitoring dasboard and get problem with incorrect template.

Reproduction Steps

        internal DashboardStack(Construct scope, string id, IStackProps props = null) : base(scope, id, props)
        {
            var dashboard = new Dashboard(this, "MonitoringDashboard", new DashboardProps
            {
                DashboardName = "MonitoringDashboard"
            });
 
            dashboard.AddWidgets(BuildWidget("dev", "Invocations", "Sum"));
        }

        private GraphWidget BuildWidget(string env, string metricName, string statistic)
        {
            IMetric metric = new Metric(new MetricProps
            {
                Namespace = "AWS/Lambda",
                Region = Region,
                Account = Account,
                Label = "functionName",
                MetricName = metricName,
                Dimensions = new Dictionary<string, object>(1) { { "FunctionName", "functionName" } },
                Statistic = statistic
            });
            var graphWidgetProps = new GraphWidgetProps
            {
                Title = metricName,
                Region = Region,
                Left = new [] { metric }
            };
            return new GraphWidget(graphWidgetProps);
        }

Error Log

The problem starts with the metrics attribute.
When I run "cdk synth" I see incorrect template with such part for metrics:

- '","metrics":[{"value":["AWS/Lambda","Invocations","FunctionName","functionName",{"label":"functionName","accountId":"'
            - Ref: AWS::AccountId
            - '","region":"'

This looks very weird indeed. Can you provide a minimal reproducing sample?

DamirAinullin · 2020-03-17T13:43:00Z

@rix0rrr I have already added the code which can lead to the problem. You can put it into sample-app and then run "cdk synth".

rix0rrr · 2020-03-18T09:47:40Z

Yes, you are right, sorry. I thought the sample was incomplete because Account and Region came out of nowhere, but obviously they're members of the Stack class. Not used to implicit this. anymore :).

Investigating.

rix0rrr · 2020-03-18T09:59:55Z

The issue seems to be that we are trying to serialize a Token (Lazy.anyValue() or other) in a position that is typed as any, and JSII doesn't like that. It should be serializing it as a reference, but it is instead serializing it as a struct:

// The following can never work
[@jsii/kernel] fromSandbox {
  type: 'metric',
  width: 6,
  height: 6,
  x: 0,
  y: 0,
  properties: {
    view: 'timeSeries',
    title: 'Invocations',
    region: '${Token[AWS::Region.4]}',
    stacked: undefined,
    metrics: [ [DropEmptyObjectAtTheEndOfAnArray] ],  // <-- this thing will go wrong
    annotations: undefined,
    yAxis: { left: undefined, right: undefined }
  }
} [{"serializationClass":"Any","typeRef":{"type":{"primitive":"any"}}}]

// When it recurses down to that object
[@jsii/kernel] fromSandbox DropEmptyObjectAtTheEndOfAnArray {
  value: [
    'AWS/Lambda',
    'Invocations',
    'FunctionName',
    'functionName',
    { label: 'functionName', stat: 'Sum' }
  ],
  creationStack: [
    // ...
    ]
} [{"serializationClass":"Any","typeRef":{"type":{"primitive":"any"}}}

The rest of the logging is not very useful but it comes down to the serializer serializing the individual fields of the token (because it's treating the token as a data type).

rix0rrr · 2020-03-18T10:00:29Z

BTW confirmed that the same code works fine in TypeScript.

rix0rrr · 2020-03-18T10:03:28Z

A "fix" would be to serialize by reference if any of the fields are functions...?

Or if the object has a prototype chain?

RomainMuller · 2020-03-18T10:28:09Z

Somehow, it appears that none of the methods of the DropEmptyObjectAtTheEndOfAnArray type (which is a private type of @aws-cdk/aws-cloudwatch not jsii-exported) come out in the enumeration at @jsii/kernel/lib/serialization.ts#L486 so they don't trigger the guard at (which would not make the problem nicer) @jsii/kernel/lib/serialization.ts#L441-L443.

A "quick fix" (CDK-side) is to introduce some jsii-exported base class and have DropEmptyObjectAtTheEndOfAnArray extend that.

Longer term - I like your idea of checking for a prototype chain and if there is one. We'll have to move carefully to make sure this does not cause any regression... So it'll probably take a little longer...

rix0rrr · 2020-03-18T10:39:23Z

Prototype chain is not good enough though, it would miss objects defined like this:

return {
  value: 'hello',
  alsoFunction() { /* do something */ },
};

return {
  value: 'hello',
  alsoFunction: () => { /* do something */ },
};

I think the only thing to do is add a check just before https://github.com/aws/jsii/blob/a2da0bfce356c2332232808d4d6eaccaf7c6d4ad/packages/%40jsii/kernel/lib/serialization.ts#L486 where we iterate the object for functions, and not just its own properties but including its prototype chain.

When a "private" type (aka a class that is not visible in the `.jsii` assembly) is passed from JS to Host through an `any`-typed entity, the value was serialized by-value, passing only the instance's properties, and omitting any methods. This changes the behavior of the `SerializationClass.Any` serializer, so that when an anonymous object is encountered, if it has a dynamic getter, setter or any method (including a constructor), it is passed by-reference instead of by-value. Fixes aws/aws-cdk#6746

RomainMuller · 2020-03-18T11:40:39Z

I have a candidate fix in aws/jsii#1347. I need to make sure it does not break some of the existing APIs that return any stuff and that must have a by-value treatment to be useful in other languages. This should (hopefully) not take too long.

It works by looking up the prototype chain for methods or dynamic property accessors (we cannot guarantee those are stable, so they get by-ref treatment, too -- it's safer).

@RomainMuller Do you have any information which version of CDK will contain the fix for this problem? And when? I tried on 1.31.0 and the problem is reproduced.

MrArnoldPalmer · 2020-04-07T20:00:05Z

@DamirAinullin the fix landed in 1.2.0 which we are working on upgrading CDK to use. This should go out in the next release.
