Error within init.lua" configuration file

[shawnbennett1221]

I'm receiving error messages with regards to configuring nvim ide using init.lua.

"Error detected while processing /home/(user name,)/.config/nvim/init.lua:
E5113: Error while calling lua chunk: /home/(usrrname)/.config/nvim/init.lua:78: attempt to index field 'keymap' (a nill value)

Stack traceback:/home/(username)/.config/nvim/init.lua:78: in main chuck

Press ENTER or type command to continue

I'm unable to proceed towards installing plug inside nvim for ide environments.
