Im shooting for an index file of just pretty 1 lines that create the objects I need

What's not working? It looks okay at first glance.

When I create a new VPC object in my index file and then create a new VPC nacl using my firewall class I can’t use the VPC ID. There is a not on the helper function it seems that says you can’t use this for building resources or using Pulumi preview. :/

That shouldn't be the case. The VPC resource provides an id that you can access.

Is it working in the Subnet you create? It's accessing vpc.id correctly.

Can you post the NACL-creating code, so we can compare?

Maybe you're accidently implicitly casting `Output&lt;string&gt;` to `any` or `string`?

BTW if it's a large about of code, the text snippet in Slack is good. It highlights syntax, and it makes a collapsible widget

Anything more than about 10 lines looks better in a snippet.

Yep, there's your problem: `vpcID: string`

`vpcID` is an `Output&lt;string&gt;`. If you cast it to `string`, it'll produce an error message, which is not a valid VPC id.

Probably the same for all the Pulumi-fetched values

If you change that to `Input&lt;string&gt;`, it'll work.

And it'll remain testable in your unit test code.

You'll need to do that for `cidr`, assuming that's calculated by AWSX.

If it's from config, or hardcoded, you'll be fine.

wait so you mean change the type to Input&lt;string&gt;

Yes. `Input&lt;string&gt;` = `string | Output&lt;string&gt;`. which is what you want.

```export class BTnacls extends pulumi.ComponentResource {
    public nacl: aws.ec2.NetworkAcl;
  
    constructor(
        naclname: string,
        vpcID: Input&lt;string&gt;,
        cidr: string,
        opts?: ResourceOptions
    ) {```

No, just use `Input&lt;string&gt;`, that's the correct type.

it doesnt like that but Ill fiddle around with it

needed to import it directly from the pulumi library

Ill get good at this language one day...just need more practice
