Shows an error when saving a file

[Icie145]

Whenever i save a file after installing neovim-cpp, This is the error i got:

Error detected while processing BufWritePre Autocommands for "<buffer=1>":
Error executing lua callback: ...ocal/share/nvim/lazy/null-ls.nvim/lua/null-ls/client.lua:35: attempt to index field '
_request_name_to_capability' (a nil value)
stack traceback:
...ocal/share/nvim/lazy/null-ls.nvim/lua/null-ls/client.lua:35: in function 'capability_is_disabled'
...ocal/share/nvim/lazy/null-ls.nvim/lua/null-ls/client.lua:43: in function 'supports_method'

Is there a way to fix this issue?
