Make NPCS play animation

[tranquil siren]

i think i might've done smth wrong here trying to make an npcs play an animation i get this error :
Unable to cast value to Object

function Modules.PlayAnimation(char : Object, AnimCodeString : string)
if char.Humanoid then
  local AnimString = "rbxassetid://" .. AnimCodeString
  local AnimTrack = char.Humanoid:LoadAnimation(AnimString)    
  AnimTrack:Play()
else
  print("Humanoid Not Found")
  return -1
end
end

probably means char isn't an object. why are you check for object anyway? shouldn't it be an instance?

[tranquil siren]

printing "char" actually prints a character of the npc tho

idk look at line 123 the problem is there

[tranquil siren]

local AnimTrack = char.Humanoid:LoadAnimation(AnimString)

here is line 123

loadanimation takes an animation object not a string, credit @frail robin
