Tsserver snippets not working

Language Server Protocol (LSP)

tsserver is not showing snippets when i type a simple word. like funtion. i gotta activate tab then only snippets is provided…

lsp config:

local capabilities = require('cmp_nvim_lsp').update_capabilities(vim.lsp.protocol.make_client_capabilities())

  vim.fn.sign_define(hl, { text = icon, texthl = hl, numhl = hl })

HELP IS NEEDED

I solved it. ahaha sorry

Can you please shortly explain what went wrong and how you fixed it?
It’d be helpful for people who finds this post in future. :smiley:

So… In my cmp there is a line which says { name = 'nvim_lsp', keyword_length = 4 }. I removed the keyword length l. DONT EVER SET KEYWORD LENGTH FOR LSP!!
