pulumi: "Channel has been shut down" errors in automation.

Expected behavior

Not getting spammed with a bunch of difficult-to-understand errors.

Current behavior

Getting a bunch of errors like:

when running an automation program

Steps to reproduce

1. Use a program like:

import { LocalWorkspace } from "@pulumi/pulumi/automation";
import * as tls from "@pulumi/tls";

async function program() {
  const privateKey = new tls.PrivateKey("test", {
    algorithm: "ECDSA",
    ecdsaCurve: "P384",
  });

  const ca = new tls.SelfSignedCert("myca", {
    privateKeyPem: privateKey.privateKeyPem,
    keyAlgorithm: privateKey.algorithm,
    allowedUses: ["cert_signing", "crl_signing"],
    validityPeriodHours: 1000 * 3600 * 24,
    subjects: [
      {
        commonName: "test.example.com",
        country: "US",
        locality: "Utah",
        organization: "Example",
      },
    ],
    isCaCertificate: true,
  });
}

async function run() {
  console.info("creating stack");
  const stack = await LocalWorkspace.createOrSelectStack({
    stackName: "dev",
    projectName: "test",
    program: program,
  });

  let command = "preview";
  if (process.argv.length > 2) {
    command = process.argv[2];
  }

  if (command == "preview") {
    console.log("Preview:");
    const result = await stack.preview({
      diff: true,
      onOutput: console.info,
    });
  } else if (command == "up") {
    const result = await stack.up({
      onOutput: console.info,
    });
  } else {
    console.error(`Unknown command ${command}`);
  }
  console.info("done");
}

run().catch((err) => console.error(err));

with a package.json like:

{
    "name": "pulumi-test",
    "main": "index.ts",
    "dependencies": {
        "@pulumi/pulumi": "^3.0.0",
        "@pulumi/tls": "^4.0.0",
        "@types/node": "^10.0.0",
        "ts-node": "^9.1.1"
    },
    "scripts": {
        "start": "./node_modules/ts-node/dist/bin.js index.ts"
    }
}

1. run npm run start up

Context (Environment)

I just ran into this while experimenting with the automation API. It looks like the rest of the program works as intended but this output makes the output very difficult to read. I also don’t know what the error means, so I’m not sure if there are other negative side effects. I’m using the local backend while experimenting.

Interestingly, if I comment out the SelfSignedCert resource, then I don’t get the error.
