Indeed, it seems quite related. Again, it looks like you are using Lua
5.1 instead of Lua 5.2:

Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio
> print(string.format("%s", true))
stdin:1: bad argument #2 to 'format' (string expected, got boolean)


Lua 5.2.1  Copyright (C) 1994-2012 Lua.org, PUC-Rio
> print(string.format("%s", true))
true
