type error when call Key.setValue()

[askdaddy]

   var ky = new Key(windef.HKEY.HKEY_CURRENT_USER, 'Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings', windef.KEY_ACCESS.KEY_WRITE);

        ky.setValue('ProxyEnable',windef.REG_VALUE_TYPE.REG_DWORD,1 );
        ky.close();

And I got a TypeError:

TypeError: Cannot read property 'deref' of undefined

PS.

C:\Users\askda\git\proxy_mgr\node_modules\windows-registry\lib\registry.js:113 result = advApi.RegSetValueExA(key.handle.deref(), valueName, null, valueType, byte.deref(), buffer.length);

byte.deref() byte was undefined

Mmmmm.... I copied this line in \node_modules\windows-registry\lib\registry.js
