Hello I am running a server and my damagelogs addon is not working, this is the error I get in console when I press f8:

[ERROR] addons/tttdamagelogs-master/lua/damagelogs/cl_damagelog.lua:137: bad argument #1 to 'IsKeyDown' (number expected, got nil)
1. IsKeyDown - [C]:-1
2. Think - addons/tttdamagelogs-master/lua/damagelogs/cl_damagelog.lua:137
3. fn - addons/tttdamagelogs-master/lua/damagelogs/cl_damagelog.lua:155
4. unknown - addons/ulib/lua/ulib/shared/hook.lua:183
