VSCode部署Bicep模板时storageName参数未解析问题求助

我尝试通过VSCode的Bicep扩展直接部署存储账户Bicep模板，但持续失败；而使用PowerShell的New-AzResourceGroupDeployment cmdlet部署则完全正常，想确认是操作有误还是存在bug。

模板中存储账户名称参数定义如下：

param storageName string = 'mystorage${uniqueString(resourceGroup().id)}'

VSCode部署时的错误 #

从VSCode部署时，storageName未自动解析，反而弹出提示要求确认该参数（点击确认后仍失败）。错误状态信息如下：

{
    "status": "Failed",
    "error": {
        "code": "AccountNameInvalid",
        "message": "[format('mystorage{0}', uniqueString(resourceGroup().id))] is not a valid storage account name. Storage account name must be between 3 and 24 characters in length and use numbers and lower-case letters only."
    }
}

可见storageName参数未被解析为实际字符串，而是直接传递了表达式，导致ARM拒绝部署。部署详情如下：

Get-AzResourceGroupDeployment -ResourceGroupName VSCodeBicepTest-RG -Name MyTestDeployment-FAILS   

DeploymentName          : MyTestDeployment-FAILS

                          storageName      String                     "[format('mystorage{0}', uniqueString(resourceGroup().id))]"

PowerShell部署正常 #

使用PowerShell部署时一切正常，部署成功，storageName参数被正确解析为字符串mystoragedcgcd6nvj5tje，部署详情如下：

New-AzResourceGroupDeployment -Name MyTestDeployment-SUCCEEDS -ResourceGroupName VSCodeBicepTest-RG -TemplateFile ./sample-template.bicep
