I noticed that if I modify the code in node_modules/@pulumi/aws/lambda/index.js like this:

function __export(m) {
    console.log(m) // <<<-------
    for (var p in m) if (!exports.hasOwnProperty(p)) {
      console.log(`Exporting ${p}`) // <<<-------
      exports[p] = m[p];
    }
}
Object.defineProperty(exports, "__esModule", { value: true });
// Export members:
console.log('Importing lambdaMixins')  // <<<-------
__export(require("./lambdaMixins"));
// ...

Then only

Importing lambdaMixins

is being printed, and none of the

Exporting ...

is printed out. Looks like some sort of circular dependency to me

Ok, solved the issue. It’s really weird. I had a code like this:

import { BucketPolicy } from '@pulumi/aws/s3'
import { getPolicyDocument } from '@pulumi/aws/iam'

const policy = getPolicyDocument(...)
new BucketPolicy(..., { ..., policy: policy.json })

I modified it to the following and it worked:

import * as aws from '@pulumi/aws'

const policy = aws.iam.getPolicyDocument(...)
new aws.s3.BucketPolicy(..., { ..., policy: policy.json })

Looks like a typescript problem
