Binding for a generic for loop in Lua | Discord Gophers | Page 1

I am writing a simple bridge for calling lua modules from Go. I have this simple loop

package main

import (
    lua "github.com/yuin/gopher-lua"
)

func main() {
    L := lua.NewState()
    defer L.Close()

    L.SetGlobal("someFunction", L.NewFunction(someFunction))

    code := `
    print("First loop")
    local x = someFunction()
    for v in x.get() do
        print("Value: " .. v)
    end
    print("Second loop")
    for v in someFunction().get() do
        print("Value: " .. v)
    end
    `

    if err := L.DoString(code); err != nil {
        panic(err)
    }
}

func someFunction(L *lua.LState) int {
    obj := L.NewTable()
    L.SetField(obj, "get", L.NewFunction(getBinding))

    L.Push(obj)
    return 1
}

func getBinding(L *lua.LState) int {
    items := []string{"Gopher", "Lua", "Go"}
    index := 0

    iterator := func(L *lua.LState) int {
        if index < len(items) {
            L.Push(lua.LString(items[index]))
            index++
            return 1
        }
        return 0
    }

    L.Push(L.NewFunction(iterator))
    return 1
}

But for some reason 1st loop works just fine but the 2nd loop fails with this error🤔

panic: <string>:8: attempt to call a non-function object
        stack traceback:
                <string>:8: in main chunk
                [G]: ?

Does anyone know what might go wrong here? And thank you in advance.
