Placeholder is not an entity type?

[Experical]

I am having a problem where it says that the placeholder is not a entity type:

every 10 seconds:
  set {playerbal} to placeholder "%factionsuuid_player_balance%"# Problem
  set {playerpower} to placeholder "%factionsuuid_player_power%"# Problem
  set {playerkills} to placeholder "%factionsuuid_player_kills%"# Problem
  set {factionname} to placeholder "%factionsuuid_faction_name%"# Problem
  set {factionpower} to placeholder "%factionsuuid_faction_power%"# Problem
  set {factionkills} to placeholder "%factionsuuid_faction_kills%"# Problem
  set {factionbal} to placeholder "%factionsuuid_faction_bank_balance%" # Problem

every second:
  loop all players:
    wipe loop-player's sidebar
    set name of sidebar of loop-player to "&9&lSkyLands"
    set score "&4&l---------------" in sidebar of loop-player to 15
    set score "&4&lPlayer Information:" in sidebar of loop-player to 14
    set score "&c&lPlayer: &6%player%" in sidebar of loop-player to 13
    set score "&c&lBalance: &6%{playerbal}%" in sidebar of loop-player to 12
    set score "&c&lPower: &6%{playerpower}%" in sidebar of loop-player to 11
    set score "&c&lKills: &6%{playerkills}%" in sidebar of loop-player to 10
    set score "&f" in sidebar of loop-player to 9
    set score "&4&lFaction Information" in sidebar of loop-player to 8
    set score "&c&lFaction Name: &6%{factionname}%" in sidebar of loop-player to 7
    set score "&c&lFaction Balance: &6%{factionbal}%" in sidebar of loop-player to 6
    set score "&c&lFaction Power: &6%{factionpower}%" in sidebar of loop-player to 5
    set score "&c&lFaction Kills: &6%{factionkills}%" in sidebar of loop-player to 4
    set score "&c" in sidebar of loop-player to 3
    set score "&4&lWebsite" in sidebar of loop-player to 2
    set score "&6combatpvp.enjin.com" in sidebar of loop-player to 1

This is the error message is attached below.
I am using Ersatz v1.0 on spigot,
