使用Bicep创建文件共享存储账户执行What-If时遇错误求助

我尝试部署一个基础文件共享存储账户（忽略注释行），通过流水线执行What-If操作时出现错误：

我已在参数文件中创建参数，并在Bicep文件顶部声明了对应正确数据类型的参数，但不清楚错误原因。以下为相关配置文件内容：

Bicep文件 #

//--Parameters--//
@description('Specifies the location for resources.')
param saLoc string

@description('Optional. Type of Storage Account to create.')
param saKind string

// The below is optional - if you want to create a fileshare stoarge account with private endpoint, you might need to give the private ip of the private endpoint here
// @description('Specifies the private IP Address of the Storage Account blob private endpoint.')
// param saBlobPrivIp string = ''

@description('Optional. Storage Account Sku Name.')

  'Standard_LRS'

  'Premium_ZRS'

param saSkuName string

param saShareQuota int

@description('Specifies the storage account to create')
param saName string

@description('Tags for the storage account')
param saTags object

@description('Array of File Shares to create')
param saFileShares array

// The below parameter is optional -  if you want to link subnet with privateendpoint
// @description('Subnet to connect Storage Account Private Endpoints')
// param saSubnet string

// The below parameter is optional - if using identity-based authentication settings for Azure Files, then uncomment the below

// @description('Optional. Provides the identity-based authentication settings for Azure Files.')
// param saazureFilesIdentityBasedAuthentication object = {}

//--Variables--//
// Loading values from the JSON file directly, some below are optional - if using private dns zone and domain, add them in envconstants file and uncomment the below
var targetEnv = loadJsonContent('../../envconstants.json', 'targetEnvironment')
// var privDNSZoneId = loadJsonContent('../../envconstants.json', 'privDNSZoneId')
// var domain = loadJsonContent('../../envconstants.json', 'domain')

// Extracting specific values from the JSON, some below are optional - if using managed domain add that in stoarge account, add that in envconstants file and uncomment this
// var privDnsZoneFileCore = privDNSZoneId.fileCore
