cdktf & Language Versions

cdktf 0.5.0
csharp 3.1/5.0

Affected Resource(s)

vsphere_virtual_machine

Expected Behavior

It should have used a bool.

Actual Behavior

It converted the bool to a string.

Steps to Reproduce

Using the code from https://github.com/rgl/dotnet-terraform-cdk-vsphere-ubuntu-example/blob/main/Main.cs#L134-L141 which is something alike;

            new VirtualMachine(this, name, new VirtualMachineConfig
            {
                Disk = new[]
                {
                    new VirtualMachineDisk
                    {
                        UnitNumber = 0,
                        Label = "os",
                        Size = Math.Max(ubuntuTemplate.Disks("0").Size, vmDiskOsSize),
                        EagerlyScrub = ubuntuTemplate.Disks("0").EagerlyScrub,
                        ThinProvisioned = ubuntuTemplate.Disks("0").ThinProvisioned,
                    },

Execute the stack with cdktf diff.

This is the error I get:

[jsteinich]

This is something that is being actively worked on. It's part of a large internal topic (#525) so it's been taking awhile, but we hope to have a resolution in the next release.

[jsteinich]

Using an escape hatch it should be possible to workaround in the meantime.

Thank you @rgl for linking such a great example! I was able verify that this problem does not exist anymore in the current version. I created an abbreviated example here: https://github.com/hashicorp/terraform-cdk/compare/verify-boolean-references-work
It compiles properly and sets all the references as we expect them to 👍
