main.lua:28: attempt to index a nil value (local 'value')

[F4IL3D]

Describe the bug
For a few days now I have not been able to run the LSP under Neovim. In order to rule out an error in Nvim or in the configuration, I tried to start the LSP directly. I get the following error message:
"/usr/lib/lua-language-server/lua-language-server: ./main.lua:28: attempt to index a nil value (local 'value') "
The same message can also be found in the neovim LSP log file.

To Reproduce
$ lua-language-server -E /usr/share/lua-language-server/main.lua

Screenshots

Environment (please complete the following information):

• OS: Windows 10, WSL2, ArchLinux , lua-language-server-git (AUR)

Additional context
I added a "print (table.concat (arg, ","))" to the beginning of the loadArgs function to see if I am doing something wrong with the arguments.
Therefore the line "--logpath=/tmp/lua-language-server.njmi/log, --metapath=/tmp/lua-language-server.njmi/meta, -E, /usr/share/lua-language-server/main.lua" can be seen in the screenshot above.

If I also add a "print(key,value)" in front of "_G[key:upper()] = value", the output looks like this

Thanks for the great work
