Gotchas

This ID is a 64-bit unsigned integer stored as a string in Lua. You should not convert this to a number in Lua because number stores values as a double-precision float which can only have 15 digits of precision. A 64-bit unsigned integer can have 20 digits, so converting this to a number can cause the trailing digits to be lost.
