Expected Behavior

Adding a new disk should work.

Actual Behavior

Error: error waiting for disk (ZXJnb24=:02bed492-4ab9-5cf2-a44b-516c9bf0d481) to be updated: error_detail: Failed to perform the operation on the VM with UUID '5d448a19-5281-4c98-6ba6-dcc7fe26b2de' because specifying both 'dataSource' and 'diskSizeBytes' is not allowed., progress_message: 100

Steps to Reproduce

1. Create a virtual machine using the configuration above
2. Add a disk by setting var.disks to a non-empty list: [40]
3. terraform apply

Important Factors

This will work if I create the additional disks right from the beginning. Adding a disk will fail.
