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

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.
