Azure RM VM with Subnets issue

[dennisrd587]

Hi there,

Thank you for opening an issue. Please note that we try to keep the Terraform issue tracker reserved for bug reports and feature requests. For general usage questions, please see: https://www.terraform.io/community.html.

Terraform Version

Terraform v0.7.13

Affected Resource(s)

azurerm_subnet

If this issue appears to affect multiple resources, it may be an issue with Terraform's core, so please mention this.

Terraform Configuration Files

### Debug Output
Please provider a link to a GitHub Gist containing the complete debug output: https://www.terraform.io/docs/internals/debugging.html. Please do NOT paste the debug output in the issue; just paste a link to the Gist.

### Panic Output
I've attached the crash log

### Expected Behavior
I'm attempting to build out a small environment in Azure

- Vnet with subnets

- resource group

- storage account

- Windows server

### Actual Behavior
I've tried to work around this by commenting out the subnets, and it seems to get past the "terramark plan", but when I uncomment them, I get the crash log

### Steps to Reproduce
Please list the steps required to reproduce the issue, for example:
1. `terraform plan`

### Important Factoids
Trying to build in an Azure RM EA subscription

### References
Are there any other GitHub issues (open or closed) or Pull Requests that should be linked here? For example:

Hi @dennisrd587

Thanks for reporting this bug - apologies for the delayed response here!

I've been able to reproduce this issue using the following Terraform config:

resource "azurerm_resource_group" "test" {
  name     = "bug10744"

After some further investigation - it looks like this is limited to the os_profile_windows_config block, as the os_profile_linux_config block has required properties.

I'm looking into this issue at the moment, and I hope to open a PR shortly :)

Thanks!
