az keyvault purge --name "{name}" hangs forever, despite key vault being successfully purged

[VladMoglan-eaton]

Describe the bug

We have a PowerShell script to create an Azure key vault in a disposable environment. In the beginning of the script, we are checking if a soft-deleted key vault exists that has the same name as the key vault we're trying to create — if it does, we purge it:

$DeletedKeyVaults = az keyvault list-deleted --query "[].name" -o json | ConvertFrom-Json

if($KeyVaultName -in $DeletedKeyVaults)
{
    Write-Host "Purging key vault '$KeyVaultName'..."
    az keyvault purge --name $KeyVaultName --location $ResourceGroupLocation
    Write-Host "Key vault '$KeyVaultName' was purged."
}

While every Azure CLI command in the script runs and successfully returns after a while, the az keyvault purge command hangs seemingly forever ("Running" is displayed on the console). The command does what it's supposed to be doing since, when checking the Azure portal, the key vault that was supposed to be purged is indeed purged as a result of running the command. It's just that the command never returns, thus allowing the script to continue.

Running the command with --debug reveals the fact that a certain request is being made in a loop, always resulting in a response with status code 202 Accepted (see debug output below).

Hi @VladMoglan-eaton,

2.58.0 is not the latest Azure CLI(2.66.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

[yonzhan]

Thank you for opening this issue, we will look into it.

Updated to latest Azure CLI version 2.66.0, issue persists.
