Invalid Index when calling key_state() in v2

[newbiemate]

describe your issue

Something with key_state() broke between v1 and v2:

check = ahk.key_state("~")

This was working fine in v1.

In v2, I got an invalid index error. The code didn't change between v1 -> v2, I only upgraded the ahk + ahk (python, v1.5.3) libraries.

ahk.version

2.0.12

AutoHotkey version

v2

Code to reproduce the issue

from ahk import AHK

ahk = AHK()
check = ahk.key_state("~")

Thanks. Confirmed the bug and reproduced. When the mode argument is not given, this bug appears when using AHK v2.

I should have a fix out for this today.

The fix for this is now released in version 1.5.4
