Cannot add VaultAliases.json entry w/o corresponding entry in Vaults.json

[aaronpburke]

If I have a default Vaults.json file (empty), the documentation states that I should be able to add a simple Vault entry to the dropdown by adding the following to VaultAliases.json (using default AAD auth). I assume this behavior is likely true for any entry in VaultAliases.json without a corresponding entry in Vaults.json:

[
  {
    "Alias": "MyVault",
    "VaultNames": [ "MyVault" ]
  }
]

But when I do, it throws the following exception:

Adding the following to Vaults.json fixes the issue:

[
  {
    "Alias": "MyVault",
    "VaultNames": [ "MyVault" ]
  }
]

This is in contrast to the documentation, which states:

Here is an example of a single vault not defined in Vaults.json

  {
    "Alias": "DEV",
    "VaultNames": [ "TestKeyVault" ]
  }

Same issue.
