Could you share your disk ID? The exception seems be caused by invalid resource ID (hence the resource group cannot be extraced).

[metaldectr]

I get diskId from vm.dataDisks()

VirtualMachine
/**
* @return the managed data disks associated with this virtual machine, indexed by LUN
*/
Map<Integer, VirtualMachineDataDisk> dataDisks();

and get Id from this object.

Would you help paste the id here (with redact if you prefer)?

I am fine with my test (with 1.36.0)

            var vm = azure.virtualMachines().getById(VM_ID);
            var id = vm.dataDisks().entrySet().iterator().next().getValue().id();

            var disk = azure.disks().getById(id);

The format of the ID would be

/subscriptions/{subscription}/resourceGroups/{resourcegroup}/providers/Microsoft.Compute/disks/{disk}
