Terraform crashes when Azure returns a azurerm_virtual_machine with empty Network interface properties

[sschne]

Hi there,

I am experiencing a crash when using Terraform v0.9.2+
The crash.log shows that a response from the Azure API returns a azurerm_virtual_machine configuration with a network Interface and an empty properties field.

The Bug was introduced with Commit

On Line 659 it is checked if NetworkInterfaceReferenceProperties is nil, which is not when a empty properties field is returned. The following attempt to access the "Primary" key is resulting in a nil pointer dereference.

I'm not sure if it is a Bug at Azure site that an empty properties field is returned. If not, it must be further checked if the properties field is empty before trying to access a key.

• azurerm_virtual_machine

Checking if "Primary" field exists before dereferencing it, tested with 0.9.11
