tsconfig.json configuration not respected

[genadis]

What happened?

I have typescript base pulumi project that has tsonfig.json with compiler options that are not respected by the pulumi action.

Example

In my typescript based pulumi project I have

import * as PACKAGE from '../../../x/package.json';

and tsconfig has "resolveJsonModule": true

no errors/warning reported by vscode linter.

when pulumi action run error is thrown:
error TS2732: Cannot find module '../../../x/package.json'. Consider using '--resolveJsonModule' to import module with '.json' extension.

Previously we used require with no issue:
const PACKAGE_VERSION = require('../../../x/package.json').version;

Output of pulumi about

ersion 3.181.0
Go Version go1.24.4
Go Compiler gc

Plugins
KIND NAME VERSION
language nodejs 3.181.0-dev.0

Hi @genadis; thanks for raising this issue and sorry you are having problems. Are you able to provide a minimal reproduction? I've just set up a new TypeScript project and this appears to work OK for me:

Pulumi.yaml

name: resolve-json
runtime: nodejs

package.json

{
  "name": "resolve-json",
  "version": "1.0.0",
  "dependencies": {
    "@pulumi/pulumi": "latest"
  },
  "devDependencies": {
    "@types/node": "^20.0.0"
  }
}

tsconfig.json

{
  "compilerOptions": {
    "resolveJsonModule": true
  }
}

index.ts

import * as PACKAGE from "./package.json"

export = async () => {
  console.log(PACKAGE.version)
}

Running prints the version from the package.json as expected:

@lunaris thank you for the reply.
I'm using the pulumi github action (not local machine).
More details about the setup:
It's lerna monorepo structured as:
packages
-> pulumi
----> src (the typescript infra code)
----> tsconfig.json
-> other-packages

simplified github action:

( inputs.work_dir is the packages/pulumi )

jobs:
  pulumi:
    runs-on: ubuntu-latest

    environment: ${{ inputs.environment }}
    
    outputs: 
        exports: ${{ toJSON(steps.pulumi.outputs) }}
    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Setup Node ${{ inputs.node_version }}
        uses: actions/setup-node@v4
        with:
          node-version: ${{ inputs.node_version }}

      - name: Install Pulumi SDK
        run: |
          cd ${{ inputs.work_dir }}
          node -v
          npm ci --ignore-scripts && npm rebuild

      - name: Configure AWS credentials
        uses: aws-actions/configure-aws-credentials@v4
        with:
          role-to-assume: ${{ inputs.aws_role_arn }}
          aws-region: ${{ inputs.aws_role_region }}

      - name: Run Pulumi command
        id: pulumi
        uses: pulumi/actions@v6
        with:
          command: ${{ inputs.command }}
          stack-name: ${{ inputs.stack_name }}
          work-dir: ${{ inputs.work_dir }}
          comment-on-summary: ${{ inputs.comment_on_summary }}
          refresh: ${{ inputs.refresh }}
        env:
          PULUMI_ACCESS_TOKEN: ${{ secrets.pulumi_token }}

Thank you for looking into this
