Create Azure Virtual Machine REST API throwing 404 for Network Interface Id

Question

Linking a Network Interface while creating a VM (using https://docs.microsoft.com/en-us/rest/api/compute/virtualmachines/createorupdate#create_a_vm_with_password_authentication.) in the same resource group as that of the Network interface throws this error (I am the owner for the Virtual Network Subnet which is attached to the Network Interface):

Error:

    "details": [],
    "code": "NotFound",
    "message": "Resource /subscriptions/40fbe15/resourceGroups/sym/providers/Microsoft.Network/networkInterfaces/deletethis374 not found."
  }
}

Answer 1

in this case the error was due to the fact that the VM and its NIC have to be in the same region. Not found error hints at that, because its looking for a combination of ID and region.
