Something Very Off Topic: LUA coding

[ThatNamibianGuy]

Hi Everyone, Hope you all staying safe and indoors where you are.

I want to ask something completely off topic, since I cannot seem to find help with it on other websites and social media.

If any of you know something about LUA coding, can you help me determine what the following error means and how to go about fixing it?

It goes as follows:

error: error: mods/1568246620_1/config/extended_gameplay/debug_mod.lua:26: bad argument #1 to 'close' (FILE* expected, got nil)
stack traceback:
[C](-1): ?
[C](-1): close
mods/1568246620_1/config/extended_gameplay/debug_mod.lua(26): clear_log
mods/1568246620_1/mod.lua(6): ?

Any help or advice will be awesome.
