I am trying to create a 
Network
from an existing VPC with this code:
Copy code
const network = infra.Network.fromVpc("network", {
    vpcId: datomicVpcId,
    subnetIds: datomicSubnets,
    publicSubnetIds: datomicSubnets,
    securityGroupIds: [appSecurityGroupId],
    usePrivateSubnets: false
});
subnetIds
and 
publicSubnetIds
are marked as 
Type 'Output<any[]>' is not assignable to type 'Input<Input<string>>[]'
. 
datomicSubnets
is defined as:
Copy code
export let datomicSubnets = datomicStorageStack.outputs.apply(o => [o["Subnet0"], o["Subnet1"], o["Subnet2"]]);
Is there a way to make this work?

something is weird with the quoting 🙂

Does this work:
Copy code
export let datomicSubnets = [
    datomicStorageStack.outputs.apply(o => o["Subnet0"]),
    datomicStorageStack.outputs.apply(o => o["Subnet1"]),
    datomicStorageStack.outputs.apply(o => o["Subnet1"]),
];
That type 
Input<Input<string>>[]
is very odd though - looks like that's probably a bug in the implementation of 
Network
? (There are two layers of 
Input
around 
string
, but none around the 
[]
as is normal)
@lemon-spoon-91807 Do you know if that type is intentional?

@white-balloon-205, this is because we have code that enumerates the subnets using .Length

But then why are there two `Input`s here?

@white-balloon-205’s solution worked.

it should either be: 
Input<string>[]
or 
Input<Input<string>[]>
.
the latter would not work for our needs though because we do resource construction based on the array length.

Right - and sounds like it needs to be the former due the the enumeration of subnets.
@white-balloon-205’s solution worked.
Great.

i will fix this up in my PR as well
the Input<Input> issue
