Description

The latest App Service Platform update added two new loadBalancing options: LeastRequestsWithTieBreaker and PerSiteRoundRobin.

A deserialize error will occur when running a PowerShell command on an app service with one of these loadBalancing options set. Command example:
$webApp = Get-AzWebApp -ResourceGroupName $RG -Name $App

The error:
Get-AzWebApp: Unable to deserialize the response.

This is a sample AZ CLI that can be used to update the loadBalancing option:
az webapp config set -g $RG -n $App --slot "staging" --generic-configurations "{'loadBalancing':'LeastRequestsWithTieBreaker'}"

@antcp and @AzureAppServiceCLI do you have any updates on when the Az.Websites PowerShell module can include the additional LeastRequestsWithTieBreaker enum?

Thanks

This is really sad that the January 2025 update did not have the fix. These new options have been present in the API definition since April 2024. @antcp and @AzureAppServiceCLI can you provide any updates?
