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

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 !

Thanks for the quick fix.
