TFS 1.X+ attempt to index local 'object' (a nil value)

[Jeyci]

I have a problem using tfs 8.6

Lua Script Error: [Scripts Interface]
C:\Users\pasterix\OneDrive\Documentos\GitHub\pro-ot\data\scripts\multiple_lever.lua:callback
...Documentos\GitHub\pro-ot\data\scripts\multiple_lever.lua:94: attempt to index local 'object' (a nil value)
stack traceback:
        ...Documentos\GitHub\pro-ot\data\scripts\multiple_lever.lua:94: in function <...Documentos\GitHub\pro-ot\data\scripts\multiple_lever.lua:61>

this is the script

--[[
    "object" -> anything that is not a floor tile.
    "floor" floor tiles (roof/ground/hole)
  
    "add" / "remove" -> tells the script what to do when lever is on the left. (after it flops, it will do the opposite)
    "replace" -> transforms an item into another item, instead of adding/removing

this is the line

 object:transform(index[4][transformTo])

this is an script that i found here maybe by xikini r sarah wesker. can't remember. how to solve the problem?

this part does works. it removes and add a wall on lever use

[59923] = {"object", "add", Position(32566, 32119, 7), 1026, "east"}, -- old
      [59923] = {"object", "add", Position(32566, 32119, 7), 1025, "east"}, -- new

here that it should create/replace an sqaure it does not

[50023] = {"floor", "replace", Position(32225, 32276, 8), {354, 427}, {false, true}}, --Lighthouse
    [50023] = {"floor", "replace", Position(32225, 32276, 8), {427, 354}, {false, true}}, --Lighthouse

tried only this but it does not work

[50023] = {"floor", "replace", Position(32225, 32276, 8), {354, 427}, {false, true}}, --Lighthouse
