Here were the outputs from the previous run to show that it did launch the first time:
```Outputs:

i haven't made any changes to the tsconfig or the sample code, i just simply tried to run it a second time.

pulumi 3.34.1
awx 0.40.0
they were the default installed when using the one-line install

and aws 5.8.0, in case it matters if i upgrade awsx version

i'm sort of confused why it would work once and then fail the second time

if i destroy and delete the stack, and then provision again, it works, but then fails on subsequent runs again

awsx 0.40 is the old version; all the docs still describe it, it's what I use. I don't think subnetSpec is part of that API, is it? I can't see it, I see just `subnets`: <https://www.pulumi.com/docs/reference/pkg/nodejs/pulumi/awsx/ec2/#VpcArgs-subnets>

<https://www.pulumi.com/docs/guides/crosswalk/aws/vpc/>

half way down the page under "Configuring Subnets for a VPC"

maybe the documenation was updated early?

Yea maybe, let's find the API for awsx 1.0.

<https://github.com/pulumi/pulumi-awsx/blob/v1.0.0-beta.8/awsx/ec2/vpc.ts>

Yep, I see SubnetSpec in there. Try changing your awsx version in package.json

i know its a beta, but its like beta 8, to me that would seem fairly stable?

maybe you're right and i should just push the version forward

It's either that or change the syntax to be 0.40 compliant. It's very similar, a minor change.

weird, <https://github.com/pulumi/pulumi-awsx/tree/v0.40.0/awsx/ec2> gives me a 404

as a first experience, this does not spark joy

Try this: <https://github.com/pulumi/pulumi-awsx/tree/v0.40.0/nodejs/awsx/ec2>

it looks like the path changed during that upgrade as well, 1.0.0 is no longer in nodejs folder

Thanks for your help <@U012UJTT55M> :+1: super appreciated sir. You provided me with a new way to discover issues as well, I didn't go read the code before but this broke the ice.
