Attempt to call field 'get_clients' (a nil value)

[fnune]

Hi! I'm getting this exception after the lsp_signature pop-up has appeared, but immediately after I type a character while the pop-up is open:

Error detected while processing function CursorHoldI_Cb[5]..CursorHoldI Autocommands for "<buffer=6>":

I met this problem, too. It seems that the function get_clients is not supported. So I went to the ~/.local/share/nvim/lazy/lsp_signature.nvim/lua/lsp_signature/init.lua file, and change the 1028 line from local clients = vim.lsp.get_clients({ bufnr = bufnr }) to local clients = vim.lsp.get_active_clients ({bufnr = bufnr}), and it works !

Looks like get_clients is Neovim 0.10+ only. 0.9 (stable) Neovim only provides get_active_clients.

So lsp_signature needs to check the Neovim version and use one of either.

See https://neovim.io/doc/user/news.html

Thanks for the quick fix.
