xRegisterStackTransform causes an error if there is no stack outputs in Typescript

[zbuchheit]

What happened?

While attempting to use xRegisterStackTransform I encountered the following error when I don't have a stack output set.

Diagnostics:

Example

Repro Code

import * as pulumi from "@pulumi/pulumi";
import * as awsx from "@pulumi/awsx";

pulumi.runtime.xRegisterStackTransform(args => {
    if (args.type === "awsx:ec2:Vpc") {
    console.log(args.name, args.type, args.props)
    }
    return undefined;
})

const vpc = new awsx.ec2.Vpc("vpc", {
    natGateways: {
        strategy: "None"
    },
});

// export const subnet = vpc.vpc.urn; //Uncomment to fix the issue

1. Run pulumi up

Additional context

This appears specific to Typescript as Python doesn't produce the same error with equivalent code.

import pulumi
from pulumi_aws import s3
import pulumi_awsx as awsx

def my_transformation(args):
    if args.type_ == "awsx:ec2:Vpc":

    return args

Similar to #15984 looks like this is something specific about component providers. We already have tests for normal resources and stack transforms without outputs that work fine.

Ah nope got a repro with just a single normal custom resource, it's just intermittent.
