Subnet cannot be assigned to network

[niklasweimann]

What happened?

I want to assign a subnet to an network, but I get an type error.

Steps to reproduce

var network = new Pulumi.HCloud.Network("Test", new Pulumi.HCloud.NetworkArgs
        {
            IpRange = "10.0.1.0/16",
            Name = "Test-Network",
        });
        var subnet = new Pulumi.HCloud.NetworkSubnet("Test-Subnet-1", new Pulumi.HCloud.NetworkSubnetArgs
        {
            IpRange = "10.0.1.0/24",
            NetworkId = network.Id,
            NetworkZone = "eu-central"
        });

Even the example from this documentation gives me the exact same type mismatch: https://www.pulumi.com/registry/packages/hcloud/api-docs/networksubnet/

Expected Behavior

I can assign the id of the network to the subnet so the subnet can correctly be created.

Actual Behavior

Type mismatch

The immediate reason for this error is a type mismatch. network.Id is a string, while NetworkId expects an integer. It could be that all is needed is a type conversion, like this:

NetworkId = network.Id.Apply(int.Parse),

If that doesn't help, could you please share the value of network.Id (e.g. log it, look it up in Pulumi state, or export it as an output0?

[niklasweimann]

Hey 👋

I just tested the .Apply(int.Parse) approach and it worked. So I would suggest updating the documentation since this really confused me as a first time user or change the type of subnet.Network to string since this seems to be an internal Id used by Pulumi only. 😊

[mikhailshilkov]

Thank you for confirming!

Id is indeed a special Pulumi property that is always assumed to be a string, while in this case it's an Integer internally. I'll leave the issue open to track the docs and/or conversion improvements.

@mikhailshilkov When using Pulumi YAML this won't work as far as I can tell. I'm fairly new to Pulumi.

[shinebayar-g]

Can this type mismatch fixed without any type conversion? This was confusing :)

[Chisnet]

This same issue is causing problems when trying to use Typescript and type conversion is icky and somewhat defeats the point of the nice TypeScript typing.

The example at https://www.pulumi.com/registry/packages/hcloud/api-docs/networksubnet/ is also invalid due to this issue.

Would love this to be resolved.
