dependsOn Doesn't Consume Helm Chart's Ready Output

[mate201]

Depends on fails to consume the helm chart's ready output.

Sorry for not being precise. I don't clearly understand generics in Typescript, so my explanation maybe is not clear, but I think the compilator error is pretty self-explanatory.

Steps to reproduce

import * as k8s from "@pulumi/kubernetes";

const chart = new k8s.helm.v3.Chart("nginx", {
    chart: "nginx",
    namespace: "blabla",
    values: {
        service: {
            type: "ClusterIP"
        }
    },
    fetchOpts: {
        repo: "https://charts.bitnami.com/bitnami"
    },
})

const abc = new k8s.core.v1.ConfigMap("test",
    {
        data: { foo: "bar" }
    }
)


const abc2 = new k8s.core.v1.ConfigMap("test",
    {
        data: { foo: "bar" }
    },
    {
        dependsOn: [abc, chart.ready],
    }
)

On the dependsOn: [abc, chart.ready] line compilator throws such error:

Type 'Output<CustomResource[]>' is not assignable to type 'Input<Resource>'.
  Type 'Output<CustomResource[]>' is not assignable to type 'OutputInstance<Resource>'.
    Types of property 'apply' are incompatible.
      Type '{ <U>(func: (t: CustomResource[]) => Promise<U>): Output<U>; <U>(func: (t: CustomResource[]) => OutputInstance<U>): Output<...>; <U>(func: (t: CustomResource[]) => U): Output<...>; }' is not assignable to type '{ <U>(func: (t: Resource) => Promise<U>): Output<U>; <U>(func: (t: Resource) => OutputInstance<U>): Output<U>; <U>(func: (t: Resource) => U): Output<...>; }'.
        Types of parameters 'func' and 'func' are incompatible.
          Types of parameters 't' and 't' are incompatible.
            Type 'CustomResource[]' is missing the following properties from type 'Resource': urn, getProviderts(2322)

This issue comes from here: #1364

I believe the issue is that ready is a pulumi.Output<pulumi.CustomResource[]>, so you can pass it alone to dependsOn: chart.ready, but if you need to add to it - you would need to do dependsOn: chart.ready.apply(ready => [abc, ...ready]).

Hello Luke,

Thank you for checking this issue. And what if I want to depend on a say three charts, like Cilium, Prometheus, and something else? At the moment I'm just using '@ts-ignore' like this:

{
    provider: ****,
    dependsOn: [
        cluster.egressNodeGroup,
        // @ts-ignore
        ciliumChart.ready,
        // @ts-ignore
        nginxChart.ready
    ]
}

It's a kludge of course, but it gives me an opportunity to spend time on different issues that are more important at the moment.
