Cannot Attach Multiple Load balancer Front End IP Configurations to an Existing Private Link Service (PLS)

[SachithKasthuriarachchi]

Describe the bug

Tried the following command to attach an additional load balancer front end IP configuration.

az network private-link-service update --lb-frontend-ip-configs <lb frontend cofig1> <lb frontend config2>  -g <resource group> -n <name of the private link service>

This resulted the following error.

(InvalidNumberOfPrivateLinkServiceLoadBalancerFrontendIpConfigurationsSpecified) Cannot have more than one load balancer frontend IP configuration on the private link service. Private link service <PLS name> has 2 load balancer frontend IP configurations specified.
Code: InvalidNumberOfPrivateLinkServiceLoadBalancerFrontendIpConfigurationsSpecified
Message: Cannot have more than one load balancer frontend IP configuration on the private link service. Private link service <PLS name> has 2 load balancer frontend IP configurations specified.

However, the docs state that we can provide space separated list of IP configurations with --lb-frontend-ip-configs option

Related command

az network private-link-service update

Errors

(InvalidNumberOfPrivateLinkServiceLoadBalancerFrontendIpConfigurationsSpecified) Cannot have more than one load balancer frontend IP configuration on the private link service. Private link service has 2 load balancer frontend IP configurations specified.
Code: InvalidNumberOfPrivateLinkServiceLoadBalancerFrontendIpConfigurationsSpecified
Message: Cannot have more than one load balancer frontend IP configuration on the private link service. Private link service has 2 load balancer frontend IP configurations specified.
