The provider event rule doesn't work. Test it with:

resource "sftpgo_rule" "mkdir" {
     name = "Create directory on user creation"
      status = 1
      trigger = 2
      conditions = {
        provider_events = ["add"]
        options = {
          provider_objects = ["user"]
        }
      }
      actions = [ {
        name = "<name of the action>"
      } ]
}
