found virtual network without ID

Error message

found virtual network without ID

What it means

Malformed-API-object guard in the Azure virtual network Find: a VNet matching by name was returned but its ID field is nil, so kOps cannot build the resource reference. Indicates a broken API response, since Azure always assigns IDs to existing resources.
