Expected Behavior

The NIC should be created with multiple nat rules assigned.

Actual Behavior

[bbc88ks]

It works if I change

load_balancer_inbound_nat_rules_ids = ["${element(azurerm_lb_nat_rule.winrm.*.id, count.index)}", "${element(azurerm_lb_nat_rule.rdp.*.id, count.index)}" ]

to:

load_balancer_inbound_nat_rules_ids = ["${element(azurerm_lb_nat_rule.winrm.*.id, count.index)}"]
