Morning all.. anyone know how to reference complex types across stacks? For example, i have subnet ids that i want to export from one stack to put in another? `Output&lt;string[]&gt;` doesn't seem to convert well to `Input&lt;string&gt;[]` (using typescript btw).

Which input property has the type `Input&lt;string&gt;[]`?

On
`awsx.ec2.ExistingVpcIdArgs`
both fields for subnetIds:
`privateSubnetIds`
`publicSubnetIds`

I suspected it was `awsx` . Usually, the type would be `pulumi.Input&lt;pulumi.Input&lt;string&gt;[]&gt;` which looks funky but accepts all combinations of outputs. awsx is sometimes missing this.

aaah right. Is there any way to coax a conversion so that i can use them?

How do you get those outputs? Are you using `getSecret`?

Any chance you can `await ref.requireOutputValue("...");` ?

it's top level atm, i mean i could do a then on the promise and do the rest of the code in a function. Not ideal tho

Yeah, this is a known challenge <https://github.com/pulumi/pulumi-awsx/issues/522>

kewl, well i'll thumbs up the issue, and probably go forward with the work around for now :slightly_smiling_face:
Thanks for the help!

that sample code in the issue is almost literally what i'm trying :slightly_smiling_face:

My "solution" to this was to merge projects and just pass the Vpc around... So far so good, only one project needs Vpcs, the others usually need individual subnetIds.

Here is an example of passing around subnet id’s from one stack to another.

<@U019AM8NP1A> thanks... unfortunately, as discussed above, the issue is in `awsx.ec2.ExistingVpcIdArgs` taking a wrong input type so that the subnet arrays being passed around don't work.
