I want to use the optional parameter to pass optional parameters:

variable "clients" {
  type = map(object({
    description         = string
    initiated_login_uri = optional(string)
    allowed_clients     = optional(list(string), [])
  }))
}

resource "auth0_client" "this" {
  for_each           = var.clients
  description        = each.value.description
  initiate_login_uri = each.value.initiated_login_uri
  allowed_clients    = each.value.allowed_clients
}

For which, as I understood I should be able to send

clients = {
  client_0 = {
    description         = "Description"
    initiated_login_uri = "http://example.com"
    allowed_clients     = ["XXXXXX"]
  },
  
  client_1 = {
    description = "Description"
  }
}

But got

all map elements must have the same type

Any way to fix that? Meaning each element of a map with non-mandatory attributes?
