I have an error in my use of TypeScript modules. Apologies for asking here, not sure where I should asking TypeScript questions... From my main index.ts (which imports and uses

@pulumi/pulumi

), I'm calling a function exported from my own module in a different project (brought in using "references": [{ "path": "../mypath/project"}] in my tsconfig.json). That function calls

pulumi.runtime.registerStackTransformation()

. That call produces this error:

Error: The root stack resource was referenced before it was initialized.

The code is good: when I lift it out of my project/module and put it directly into index.ts it works fine. I'm guessing that this is a scoping issue. Question: how do I call Pulumi code from projects/modules that are outside my application's project? Should I be passing "pulumi" or "pulumi.runtime" from my main module into my referenced project?

Can you elaborate on how you're calling this external function?

It's an internal library in a separate codebase. The library's tsconfig includes this (don't know what half of it does, I just lifted it from a similar library):

"compilerOptions": {
        "composite": true,
        "declaration": true,
        "declarationMap": true,
        "strict": true,
        "target": "es2017",
        "module": "esnext",
        "moduleResolution": "node",

The module in the library just exports a function,

registerAutoTags

The app project's tsconfig includes this:

"references": [
        {
            "path": "../pulumi"
        }

And the app's index.ts has this:

import { registerAutoTags } from "../../pulumi/autotag/autotag";

// Automatically inject tags.
registerAutoTags({
  "user:Project": pulumi.getProject(),
  "user:Stack": pulumi.getStack(),
  "Env": "Sandbox",
});

And you're running this application with the Pulumi cli? e.g.

pulumi up

Yep. I'm seeing this with

pulumi preview

. I didn't know there was another way to run it...

There isn't. I wanted to make sure you were doing it that way.

I'm running Pulumi 2.1.1 via the pulumi/pulumi Docker image.

Is

registerAutoTags()

called before all Pulumi resource creations?

Yes, it's the first non-import in my index.ts.
