Any other comments?

It may be because I don't know Lua very much, but I'm not sure why a global variable of type string is typed differently than a local variable of type string. Moreover, if I use a type cast (--[[---@type string]]) it works, and I don't understand why it changes anything.

Or maybe this is due to the fact that there are other files in the project that assign to the same global variable ? They are also all assigning strings.
