How to link_to_unmanaged_keyvault in functions builder

[simsoll]

Hello,

I'm trying to use an existing non-Farmer managed Key Vault when creating my Functions App template. I've come up with the following simple example

open Farmer
open Farmer.Builders

let plan = servicePlan {
    name "plan-func-apps"
    sku WebApp.Sku.EP1
    max_elastic_workers 25
}

let myExistingKeyVault = 
    ResourceId.create (
        Arm.KeyVault.vaults,
        "kv-my-key-vault" |> ResourceName,
        "rg-key-vault"
    )

let func = functions {
    link_to_service_plan plan.Name
    link_to_unmanaged_keyvault myExistingKeyVault
    name "func-my-func"
    secret_setting "MySecret"
}

let deployment = arm {
    location Location.WestEurope
    add_resource plan
    add_resource func
}

deployment
|> Writer.quickWrite "arm"

When I try to deploy the generated template using

New-AzResourceGroupDeployment -ResourceGroupName 'rg-func-apps' -TemplateFile arm.json

I get the following validation error

Error: Code=InvalidTemplate; Message=Deployment template validation failed: 'The resource 'Microsoft.KeyVault/vaults/kv-my-key-vault' is not defined in the template. Please see https://aka.ms/arm-template for usage details.'.

Am I missing something when linking to the unmanaged Key Vault?

Hey @simsoll. This looks like a bug then as an unmanaged keyvault shouldn't be needed within the template. Could you raise an issue and link to this discussion? Thanks!
