Debug Output

Panic Output

Expected Behaviour

Terraform should perform the add/update/delete of NAT IP configuration only

Actual Behaviour

Terraform deletes and recreates the entire Private link with the new NAT IP configuration

Steps to Reproduce

1. add/update/delete any Private Link Service nat_ip_configuration
2. terraform apply

References

1. Add/update/delete NAT IP configuration is currently already supportted https://docs.microsoft.com/en-gb/rest/api/virtualnetwork/privatelinkservices/createorupdate#privatelinkserviceipconfiguration
