Hii community,

I am trying to create a storage account with multiple file shares with a single form of variables. currently I am trying by map of list of objects like below:

variable "StorageAccount" {
  type = map(map(list(object({
    FileShare = string
    Quota = number
    Tier = string
  }))))
}

StorageAccount = {
  "sa1" = {
    "FS" = [{
      FileShare = "File1"
      Quota = 50
      Tier = "Hot"
    },
    {
      FileShare = "File2"
      Quota = 50
      Tier = "Hot"
    }]
  },
  "sa2" = {
    "FS" = [{
      FileShare = "File1"
      Quota = 50
      Tier = "Hot"
    },
    {
      FileShare = "File2"
      Quota = 50
      Tier = "Hot"
    }]
  }
}

here I am trying to create sa1 storage account and FS is object to create fileshares.
but Its not working as I expected.
Can someone help me achieve my goal ??
